  56             <function>glGetProgramResourceiv</function> returns values for multiple properties of a single active resource with an
  57             index of <parameter>index</parameter> in the interface <parameter>programInterface</parameter> of program object
  58             <parameter>program</parameter>.  For each resource, values for <parameter>propCount</parameter> properties specified
  59             by the array <parameter>props</parameter> are returned.  <parameter>propCount</parameter> may not be zero.
  60             An error is generated if any value

 210         <para>
 211             For the property <constant>GL_NAME_LENGTH</constant>, a single integer identifying the length of
 212             the name string associated with an active variable, interface block, or
 213             subroutine is written to <parameter>params</parameter>.  The name length includes a terminating
 214             null character.
 215
 216             For the property <constant>GL_TYPE</constant>, a single integer identifying the type of an active
 217             variable is written to <parameter>params</parameter>.  The integer returned is one of the
 218             values found in table 2.16.
 219
 220             For the property <constant>GL_ARRAY_SIZE</constant>, a single integer identifying the number of
 221             active array elements of an active variable is written to <parameter>params</parameter>.  The
 222             array size returned is in units of the type associated with the property
 223             TYPE.  For active variables not corresponding to an array of basic types,
 224             the value zero is written to <parameter>params</parameter>.
 225
 226             For the property <constant>GL_BLOCK_INDEX</constant>, a single integer identifying the index of
 227             the active interface block containing an active variable is written to
 228             <parameter>params</parameter>.  If the variable is not the member of an interface block, the
 229             value -1 is written to <parameter>params</parameter>.
 230
 231             For the property <constant>GL_OFFSET</constant>, a single integer identifying the offset of an
 232             active variable is written to <parameter>params</parameter>.  For active variables backed by a
 233             buffer object, the value written is the offset, in basic machine units,
 234             relative to the base of buffer range holding the values of the variable.
 235             For active variables not backed by a buffer object, an offset of -1 is
 236             written to <parameter>params</parameter>.
 237
 238             For the property <constant>GL_ARRAY_STRIDE</constant>, a single integer identifying the stride
 239             between array elements in an active variable is written to <parameter>params</parameter>.  For
 240             active variables declared as an array of basic types, the value written is
 241             the difference, in basic machine units, between the offsets of consecutive
 242             elements in an array.  For active variables not declared as an array of
 243             basic types, zero is written to <parameter>params</parameter>.  For active variables not backed
 244             by a buffer object, -1 is written to <parameter>params</parameter>, regardless of the variable
 245             type.
 246
 247             For the property <constant>GL_MATRIX_STRIDE</constant>, a single integer identifying the stride
 248             between columns of a column-major matrix or rows of a row-major matrix is
 249             written to <parameter>params</parameter>.  For active variables declared a single matrix or
 250             array of matrices, the value written is the difference, in basic machine
 251             units, between the offsets of consecutive columns or rows in each matrix.
 252             For active variables not declared as a matrix or array of matrices, zero
 253             is written to <parameter>params</parameter>.  For active variables not backed by a buffer
 254             object, -1 is written to <parameter>params</parameter>, regardless of the variable type.
 255
 256             For the property <constant>GL_IS_ROW_MAJOR</constant>, a single integer identifying whether an
 257             active variable is a row-major matrix is written to <parameter>params</parameter>.  For active
 258             variables backed by a buffer object, declared as a single matrix or array
 259             of matrices, and stored in row-major order, one is written to <parameter>params</parameter>.
 260             For all other active variables, zero is written to <parameter>params</parameter>.
 261
 262             For the property <constant>GL_ATOMIC_COUNTER_BUFFER_INDEX</constant>, a single integer identifying
 263             the index of the active atomic counter buffer containing an active
 264             variable is written to <parameter>params</parameter>.  If the variable is not an atomic counter
 265             uniform, the value -1 is written to <parameter>params</parameter>.
 266
 267             For the property <constant>GL_BUFFER_BINDING</constant>, to index of the buffer binding point
 268             associated with the active uniform block, shader storage block, or atomic
 269             counter buffer is written to <parameter>params</parameter>.
 270
 271             For the property <constant>GL_BUFFER_DATA_SIZE</constant>, then the implementation-dependent
 272             minimum total buffer object size, in basic machine units, required to hold
 273             all active variables associated with an active uniform block, shader
 274             storage block, or atomic counter buffer is written to <parameter>params</parameter>.  If the
 275             final member of an active shader storage block is array with no declared
 276             size, the minimum buffer size is computed assuming the array was declared
 277             as an array with one element.
 278
 279             For the property <constant>GL_NUM_ACTIVE_VARIABLES</constant>, the number of active variables
 280             associated with an active uniform block, shader storage block, or atomic
 281             counter buffer is written to <parameter>params</parameter>.
 282
 283             For the property <constant>GL_of ACTIVE_VARIABLES</constant>, an array of active variable indices
 284             associated with an active uniform block, shader storage block, or atomic
 285             counter buffer is written to <parameter>params</parameter>.  The number of values written to
 286             <parameter>params</parameter> for an active resource is given by the value of the property
 287             <constant>GL_NUM_ACTIVE_VARIABLES</constant> for the resource.
 288
 289             For the properties <constant>GL_REFERENCED_BY_VERTEX_SHADER</constant>,
 290             <constant>GL_REFERENCED_BY_TESS_CONTROL_SHADER</constant>, <constant>GL_REFERENCED_BY_TESS_EVALUATION_SHADER</constant>,
 291             <constant>GL_REFERENCED_BY_GEOMETRY_SHADER</constant>, <constant>GL_REFERENCED_BY_FRAGMENT_SHADER</constant>, and
 292             <constant>GL_REFERENCED_BY_COMPUTE_SHADER</constant>, a single integer is written to <parameter>params</parameter>,
 293             identifying whether the active resource is referenced by the vertex,
 294             tessellation control, tessellation evaluation, geometry, or fragment
 295             shaders, respectively, in the program object.  The value one is written to
 296             <parameter>params</parameter> if an active variable is referenced by the corresponding shader,
 297             or if an active uniform block, shader storage block, or atomic counter
 298             buffer contains at least one variable referenced by the corresponding
 299             shader.  Otherwise, the value zero is written to <parameter>params</parameter>.
 300
 301             For the property <constant>GL_TOP_LEVEL_ARRAY_SIZE</constant>, a single integer identifying the
 302             number of active array elements of the top-level shader storage block
 303             member containing to the active variable is written to <parameter>params</parameter>.  If the
 304             top-level block member is not declared as an array, the value one is
 305             written to <parameter>params</parameter>.  If the top-level block member is an array with no
 306             declared size, the value zero is written to <parameter>params</parameter>.
 307
 308             For the property <constant>GL_TOP_LEVEL_ARRAY_STRIDE</constant>, a single integer identifying the
 309             stride between array elements of the top-level shader storage block member
 310             containing the active variable is written to <parameter>params</parameter>.  For top-level
 311             block members declared as arrays, the value written is the difference, in
 312             basic machine units, between the offsets of the active variable for
 313             consecutive elements in the top-level array.  For top-level block members
 314             not declared as an array, zero is written to <parameter>params</parameter>.
 315
 316             For the property <constant>GL_LOCATION</constant>, a single integer identifying the assigned
 317             location for an active uniform, input, output, or subroutine uniform
 318             variable is written to <parameter>params</parameter>.  For input, output, or uniform variables
 319             with locations specified by a layout qualifier, the specified location is
 320             used.  For vertex shader input or fragment shader output variables without
 321             a layout qualifier, the location assigned when a program is linked is
 322             written to <parameter>params</parameter>.  For all other input and output variables, the value
 323             -1 is written to <parameter>params</parameter>.  For uniforms in uniform blocks, the value -1
 324             is written to <parameter>params</parameter>.
 325
 326             For the property <constant>GL_LOCATION_INDEX</constant>, a single integer identifying the fragment
 327             color index of an active fragment shader output variable is written to
 328             <parameter>params</parameter>.  If the active variable is an output for a non-fragment shader,
 329             the value -1 will be written to <parameter>params</parameter>.
 330
 331             For the property <constant>GL_IS_PER_PATCH</constant>, a single integer identifying whether the
 332             input or output is a per-patch attribute.  If the active variable is a
 333             per-patch attribute (declared with the <code>patch</code> qualifier), the value one
 334             is written to <parameter>params</parameter>; otherwise, the value zero is written to <parameter>params</parameter>.
