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
