NAME
glPushName, glPopName - push and pop the name stack
C SPECIFICATION
void glPushName( GLuint name )
PARAMETERS
name Specifies a name that will be pushed onto the name stack.
C SPECIFICATION
void glPopName( void )
DESCRIPTION
The name stack is used during selection mode to allow sets of rendering
commands to be uniquely identified. It consists of an ordered set of
unsigned integers and is initially empty.
glPushName causes name to be pushed onto the name stack. glPopName pops
one name off the top of the stack.
The maximum name stack depth is implementation-dependent; call
GLMAXNAMESTACKDEPTH to find out the value for a particular
implementation. It is an error to push a name onto a full stack, or to
pop a name off an empty stack. It is also an error to manipulate the
name stack between the execution of glBegin and the corresponding
execution of glEnd. In any of these cases, the error flag is set and no
other change is made to GL state.
The name stack is always empty while the render mode is not GLSELECT.
Calls to glPushName or glPopName while the render mode is not GLSELECT
are ignored.
ERRORS
GLSTACKOVERFLOW is generated if glPushName is called while the name
stack is full.
GLSTACKUNDERFLOW is generated if glPopName is called while the name
stack is empty.
GLINVALIDOPERATION is generated if glPushName or glPopName is executed
between a call to glBegin and the corresponding call to glEnd.
