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 render-
       ing 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 imple-
       mentation. 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	 exe-
       cuted between a call to glBegin and the corresponding call to glEnd.
