41 <function>glIsProgramPipeline
</function> returns
<constant>GL_TRUE
</constant> if
42 <parameter>pipeline
</parameter> is currently the name of a program pipeline object.
43 If
<parameter>pipeline
</parameter> is zero, or if
<constant>pipeline
</constant> is not the
44 name of a program pipeline object, or if an error occurs,
<function>glIsProgramPipeline
</function>
45 returns
<constant>GL_FALSE
</constant>. If
<parameter>pipeline
</parameter> is a name returned by
46 <citerefentry><refentrytitle>glGenProgramPipelines
</refentrytitle></citerefentry>, but that
47 has not yet been bound through a call to
<citerefentry><refentrytitle>glBindProgramPipeline
</refentrytitle></citerefentry>,
48 then the name is not a program pipeline object and
<function>glIsProgramPipeline
</function>
49 returns
<constant>GL_FALSE
</constant>.
