GLPUSHATRIB(3G)                                              GLPUSHATRIB(3G)



NAME
       glPushAttrib,, glPopAttrib - push and pop the server attribute stack


C SPECIFICATION
       void glPushAttrib( GLbitfield mask )


PARAMETERS
       mask  Specifies  a mask that indicates which attributes to save. Values
             for mask are listed below.

C SPECIFICATION
       void glPopAttrib( void )


DESCRIPTION
       glPushAttrib takes one argument, a mask that indicates which groups  of
       state variables to save on the attribute stack.  Symbolic constants are
       used to set bits in the mask.  mask is typically constructed  by  ORing
       several    of    these    constants   together.    The   special   mask
       GLALATRIBITS can be used to save all stackable states.

       The symbolic mask constants and their associated GL state are  as  fol-
       lows (the second column lists which attributes are saved):
