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.

NAME

       glGetShaderiv - Returns a parameter from a shader object

C SPECIFICATION

       void glGetShaderiv(GLuint shader, GLenum pname, GLint *params);

PARAMETERS

       shader
	   Specifies the shader object to be queried.

       pname
	   Specifies the object parameter. Accepted symbolic names are GL_SHADER_TYPE, GL_DELETE_STATUS, GL_COMPILE_STATUS, GL_INFO_LOG_LENGTH,
	   GL_SHADER_SOURCE_LENGTH.

       params
	   Returns the requested object parameter.

DESCRIPTION

       glGetShader returns in params the value of a parameter for a specific shader object. The following parameters are defined:

       GL_SHADER_TYPE

	   params returns GL_VERTEX_SHADER if shader is a vertex shader object, GL_GEOMETRY_SHADER if shader is a geometry shader object, and
	   GL_FRAGMENT_SHADER if shader is a fragment shader object.

       GL_DELETE_STATUS

	   params returns GL_TRUE if shader is currently flagged for deletion, and GL_FALSE otherwise.

       GL_COMPILE_STATUS

	   params returns GL_TRUE if the last compile operation on shader was successful, and GL_FALSE otherwise.

       GL_INFO_LOG_LENGTH

	   params returns the number of characters in the information log for shader including the null termination character (i.e., the size of
	   the character buffer required to store the information log). If shader has no information log, a value of 0 is returned.

       GL_SHADER_SOURCE_LENGTH

	   params returns the length of the concatenation of the source strings that make up the shader source for the shader, including the null
	   termination character. (i.e., the size of the character buffer required to store the shader source). If no source code exists, 0 is
	   returned.

NOTES

       If an error is generated, no change is made to the contents of params.

ERRORS

       GL_INVALID_VALUE is generated if shader is not a value generated by OpenGL.

       GL_INVALID_OPERATION is generated if shader does not refer to a shader object.

       GL_INVALID_ENUM is generated if pname is not an accepted value.
