GLGETPROGRAMPIPELINE(3G)	 OpenGL 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.
