GLVALIDATEPROGRAMPIP(3G)					   OpenGL Manual					  GLVALIDATEPROGRAMPIP(3G)

NAME

       glValidateProgramPipeline - validate a program pipeline object against current GL state

C SPECIFICATION

       void glValidateProgramPipeline(GLuint pipeline);

PARAMETERS

       pipeline
	   Specifies the name of a program pipeline object to validate.

DESCRIPTION

       glValidateProgramPipeline instructs the implementation to validate the shader executables contained in pipeline 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 GL_TRUE. The validation status of a program pipeline object
       may be queried by calling glGetProgramPipeline() with parameter GL_VALIDATE_STATUS.

       If pipeline is a name previously returned from a call to glGenProgramPipelines() but that has not yet been bound by a call to
       glBindProgramPipeline(), a new program pipeline object is created with name pipeline and the default state vector.

ERRORS

       GL_INVALID_OPERATION is generated if pipeline is not a name previously returned from a call to glGenProgramPipelines() or if such a name
       has been deleted by a call to glDeleteProgramPipelines().

ASSOCIATED GETS

       glGetProgramPipeline() with parameter GL_VALIDATE_STATUS.

SEE ALSO

       glGenProgramPipelines(), glBindProgramPipeline(), glDeleteProgramPipelines()
