GLPUSHNAME(3G)							GLPUSHNAME(3G)

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
       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.

ERRORS
       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.

ASSOCIATED GETS
       glGet with argument GL_NAME_STACK_DEPTH
       glGet with argument GL_MAX_NAME_STACK_DEPTH
