fglPushName(3G) OpenGL Reference fglPushName(3G)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.
