glPushName, glPopName - push and pop the name stack
void
glPushName( GLuint name )
- name
- Specifies a name that will be pushed onto the name stack.
void glPopName( void )
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
GL_MAX_NAME_STACK_DEPTH 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 GL_SELECT.
Calls to glPushName or glPopName while the render mode is not GL_SELECT
are ignored.
GL_STACK_OVERFLOW is generated if glPushName is called
while the name stack is full.
GL_STACK_UNDERFLOW is generated if glPopName
is called while the name stack is empty.
GL_INVALID_OPERATION is generated
if glPushName or glPopName is executed between a call to glBegin and the
corresponding call to glEnd.
