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.
