NAME
fglPushName, fglPopName - push and pop the name stack
FORTRAN SPECIFICATION
SUBROUTINE fglPushName( INTEGER*4 name )
PARAMETERS
name Specifies a name that will be pushed onto the name
stack.
FORTRAN SPECIFICATION
SUBROUTINE fglPopName( )
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.
fglPushName causes name to be pushed onto the name stack.
fglPopName 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 fglBegin and the corresponding execution of
fglEnd. 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 fglPushName or fglPopName while the
render mode is not GL_SELECT are ignored.
ERRORS
GL_STACK_OVERFLOW is generated if fglPushName is called
while the name stack is full.
GL_STACK_UNDERFLOW is generated if fglPopName is called
while the name stack is empty.
GL_INVALID_OPERATION is generated if fglPushName or
fglPopName is executed between a call to fglBegin and the
corresponding call to fglEnd.
ASSOCIATED GETS

fglGet with argument GL_MAX_NAME_STACK_DEPTH
