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

NAME
glGetProgramStage - retrieve properties of a program object corresponding to a specified shader stage C SPECIFICATION
void glGetProgramStageiv(GLuint program, GLenum shadertype, GLenum pname, GLint *values); PARAMETERS
program Specifies the name of the program containing shader stage. shadertype Specifies the shader stage from which to query for the subroutine parameter. shadertype must be one of GL_VERTEX_SHADER, GL_TESS_CONTROL_SHADER, GL_TESS_EVALUATION_SHADER, GL_GEOMETRY_SHADER or GL_FRAGMENT_SHADER. pname Specifies the parameter of the shader to query. pname must be GL_ACTIVE_SUBROUTINE_UNIFORMS, GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS, GL_ACTIVE_SUBROUTINES, GL_ACTIVE_SUBROUTINE_UNIFORM_MAX_LENGTH, or GL_ACTIVE_SUBROUTINE_MAX_LENGTH. values Specifies the address of a variable into which the queried value or values will be placed. DESCRIPTION
glGetProgramStage queries a parameter of a shader stage attached to a program object. program contains the name of the program to which the shader is attached. shadertype specifies the stage from which to query the parameter. pname specifies which parameter should be queried. The value or values of the parameter to be queried is returned in the variable whose address is given in values. If pname is GL_ACTIVE_SUBROUTINE_UNIFORMS, the number of active subroutine variables in the stage is returned in values. If pname is GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS, the number of active subroutine variable locations in the stage is returned in values. If pname is GL_ACTIVE_SUBROUTINES, the number of active subroutines in the stage is returned in values. If pname is GL_ACTIVE_SUBROUTINE_UNIFORM_MAX_LENGTH, the length of the longest subroutine uniform for the stage is returned in values. If pname is GL_ACTIVE_SUBROUTINE_MAX_LENGTH, the length of the longest subroutine name for the stage is returned in values. The returned name length includes space for the null-terminator. If there is no shader present of type shadertype, the returned value will be consistent with a shader containing no subroutines or subroutine uniforms. ERRORS
GL_INVALID_ENUM is generated if shadertype or pname is not one of the accepted values. GL_INVALID_VALUE is generated if program is not the name of an existing program object. SEE ALSO
