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.
