GLGETPROGRAMPIPELINE(3G) [FIXME: manual] GLGETPROGRAMPIPELINE(3G) NAME
glGetProgramPipeline - retrieve properties of a program pipeline object C SPECIFICATION
void glGetProgramPipelineiv(GLuint pipeline, GLenum pname, GLint *params); PARAMETERS
pipeline Specifies the name of a program pipeline object whose parameter retrieve. pname Specifies the name of the parameter to retrieve. params Specifies the address of a variable into which will be written the value or values of pname for pipeline. DESCRIPTION
glGetProgramPipelineiv retrieves the value of a property of the program pipeline object pipeline. pname specifies the name of the parameter whose value to retrieve. The value of the parameter is written to the variable whose address is given by params. If pname is GL_ACTIVE_PROGRAM, the name of the active program object of the program pipeline object is returned in params. If pname is GL_VERTEX_SHADER, the name of the current program object for the vertex shader type of the program pipeline object is returned in params. If pname is GL_TESS_CONTROL_SHADER, the name of the current program object for the tessellation control shader type of the program pipeline object is returned in params. If pname is GL_TESS_EVALUATION_SHADER, the name of the current program object for the tessellation evaluation shader type of the program pipeline object is returned in params. If pname is GL_GEOMETRY_SHADER, the name of the current program object for the geometry shader type of the program pipeline object is returned in params. If pname is GL_FRAGMENT_SHADER, the name of the current program object for the fragment shader type of the program pipeline object is returned in params. If pname is GL_INFO_LOG_LENGTH, the length of the info log, including the null terminator, is returned in params. If there is no info log, zero is returned. ERRORS
GL_INVALID_OPERATION is generated if pipeline is not zero or a name previously returned from a call to glGenProgramPipelines() or if such a name has been deleted by a call to glDeleteProgramPipelines(). GL_INVALID_ENUM is generated if pname is not one of the accepted values. SEE ALSO

GLUSEPROGRAMSTAGES(3G) [FIXME: manual] GLUSEPROGRAMSTAGES(3G) 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, and GL_FRAGMENT_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. 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().
