glUseProgramStages — bind stages of a program object to a program pipeline
void glUseProgramStages( | GLuint pipeline, |
GLbitfield stages, | |
GLuint program) ; |
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
.
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_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.
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.
