+ <code class="function">glProgramBinary</code> loads a program object with a program binary previously
+ returned from <a href="glGetProgramBinary.xml"><span class="citerefentry"><span class="refentrytitle">glGetProgramBinary</span></span></a>.
+ <em class="parameter"><code>binaryFormat</code></em> and <em class="parameter"><code>binary</code></em> must be those returned
+ by a previous call to <a href="glGetProgramBinary.xml"><span class="citerefentry"><span class="refentrytitle">glGetProgramBinary</span></span></a>,
+ and <em class="parameter"><code>length</code></em> must be the length returned by
+ <a href="glGetProgramBinary.xml"><span class="citerefentry"><span class="refentrytitle">glGetProgramBinary</span></span></a>, or by
+ <a href="glGetProgram.xml"><span class="citerefentry"><span class="refentrytitle">glGetProgram</span></span></a> when called with
+ <em class="parameter"><code>pname</code></em> set to <code class="constant">GL_PROGRAM_BINARY_LENGTH</code>.
+ If these conditions are not met, loading the program binary will fail and <em class="parameter"><code>program</code></em>'s
+ <code class="constant">GL_LINK_STATUS</code> will be set to <code class="constant">GL_FALSE</code>.
+ </p><p>
+ A program object's program binary is replaced by calls to
+ <a href="glLinkProgram.xml"><span class="citerefentry"><span class="refentrytitle">glLinkProgram</span></span></a> or
+ <code class="function">glProgramBinary</code>. When linking success or failure is concerned, <code class="function">glProgramBinary</code>
+ can be considered to perform an implicit linking operation.
+ <a href="glLinkProgram.xml"><span class="citerefentry"><span class="refentrytitle">glLinkProgram</span></span></a> and <code class="function">glProgramBinary</code>
+ both set the program object's <code class="constant">GL_LINK_STATUS</code> to <code class="constant">GL_TRUE</code>
+ or <code class="constant">GL_FALSE</code>.
+ </p><p>
+ A successful call to <code class="function">glProgramBinary</code> will reset all uniform variables to their
+ initial values. The initial value is either the value of the variable's initializer as specified in the
+ original shader source, or zero if no initializer was present. Additionally, all vertex shader input
+ and fragment shader output assignments that were in effect when the program was linked before saving are
+ restored with <code class="function">glProgramBinary</code> is called.
+ </p></div><div class="refsect1" lang="en" xml:lang="en"><a id="errors"></a><h2>Errors</h2><p>
+ <code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>program</code></em> is not the
+ name of an existing program object.

+ <code class="constant">GL_INVALID_ENUM</code> is generated if <em class="parameter"><code>binaryFormat</code></em> is not a
+ value recognized by the implementation.

+ A program binary may fail to load if the implementation determines that there has been a
+ change in hardware or software configuration from when the program binary was produced such
+ as having been compiled with an incompatible or outdated version of the compiler.
