NAME

       glUseProgramStages - bind stages of a program object to a program pipeline

C SPECIFICATION

       void glUseProgramStages(GLuint pipeline, GLbitfield stages, GLuint program);

PARAMETERS

       pipeline
	   Specifies the program pipeline object to which to bind stages from program.

       stages
	   Specifies a set of program stages to bind to the program pipeline object.

       program
	   Specifies the program object containing the shader executables to use in pipeline.

DESCRIPTION

       glUseProgramStages binds executables from a program object associated with a specified set of shader stages to the program pipeline object
       given by pipeline.  pipeline specifies the program pipeline object to which to bind the executables.  stages contains a logical combination
       of bits indicating the shader stages to use within program with the program pipeline object pipeline.  stages must be a logical combination
       of GL_VERTEX_SHADER_BIT, GL_TESS_CONTROL_SHADER_BIT, GL_TESS_EVALUATION_SHADER_BIT, GL_GEOMETRY_SHADER_BIT, GL_FRAGMENT_SHADER_BIT and
       GL_COMPUTE_SHADER_BIT. Additionally, the special value GL_ALL_SHADER_BITS may be specified to indicate that all executables contained in
       program should be installed in pipeline.

       If program refers to a program object with a valid shader attached for an indicated shader stage, glUseProgramStages installs the
       executable code for that stage in the indicated program pipeline object pipeline. If program is zero, or refers to a program object with no
       valid shader executable for a given stage, it is as if the pipeline object has no programmable stage configured for the indicated shader
       stages. If stages contains bits other than those listed above, and is not equal to GL_ALL_SHADER_BITS, an error is generated.

NOTES

       The GL_COMPUTE_SHADER_BIT bit is available only if the GL version is 4.3 or greater.

ERRORS

       GL_INVALID_VALUE is generated if shaders contains set bits that are not recognized, and is not the reserved value GL_ALL_SHADER_BITS.

       GL_INVALID_OPERATION is generated if program refers to a program object that was not linked with its GL_PROGRAM_SEPARABLE status set.

       GL_INVALID_OPERATION is generated if program refers to a program object that has not been successfully linked.

       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().
