glPushName.3gl




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.  glPushName causes	name to	be pushed onto the name
  stack, which is initially empty.  glPopName pops one name off	the top	of
  the stack.

  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
