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.
