<para>
|

<function>glValidateProgramPipeline</function> instructs the implementation to validate the
|
|
shader executables contained in <parameter>pipeline</parameter> against the current GL state.
|
|
The implementation may use this as an opportunity to perform any internal shader modifications
|
|
that may be required to ensure correct operation of the installed shaders given the
|
|
current GL state.

After a program pipeline has been validated, its validation status is set to <constant>GL_TRUE</constant>.
|
|
The validation status of a program pipeline object may be queried by calling
|
|
<citerefentry><refentrytitle>glGetProgramPipeline</refentrytitle></citerefentry> with
|
|
parameter <constant>GL_VALIDATE_STATUS</constant>.

that has not yet been bound by a call to <citerefentry><refentrytitle>glBindProgramPipeline</refentrytitle></citerefentry>,
|
|
a new program pipeline object is created with name <parameter>pipeline</parameter> and

the default state vector.
