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().
