void GLAPIENTRY glPushClientAttrib( GLbitfield mask );  /* 1.1 )

PARAMETERS
       1.1  Specifies a mask that indicates which attributes to  save.   Values
            for 1.1 are listed below.

C SPECIFICATION
       void GLAPIENTRY glPopClientAttrib( void );  /* 1.1 )

DESCRIPTION
       glPushClientAttrib  takes  one  argument,  a  mask  that indicates which
       groups of client-state variables to save on the client attribute  stack.
       Symbolic  constants  are used to set bits in the mask.  1.1 is typically
       constructed by OR'ing several of these constants together.  The  special
       mask  GL_CLIENT_ALL_ATTRIB_BITS can be used to save all stackable client
       state.

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

       GL_CLIENT_PIXEL_STORE_BIT     Pixel storage modes
       GL_CLIENT_VERTEX_ARRAY_BIT    Vertex arrays (and enables)

       glPopClientAttrib  restores  the  values  of  the client-state variables
       saved with the last glPushClientAttrib.  Those not saved  are  left  un‐
       changed.

       It is an error to push attributes onto a full client attribute stack, or
       to pop attributes off an empty stack.  In either case, the error flag is
       set, and no other change is made to GL state.

       Initially, the client attribute stack is empty.

NOTES
       glPushClientAttrib  is  available  only  if  the  GL  version  is 1.1 or
       greater.

       Not all values for GL client state can be saved on the attribute  stack.
       For example, select and feedback state cannot be saved.

       The  depth  of the attribute stack depends on the implementation, but it
       must be at least 16.

       Use glPushAttrib and glPopAttrib to push and restore state which is kept
       on  the  server.  Only pixel storage modes and vertex array state may be
       pushed and popped with glPushClientAttrib and glPopClientAttrib.

       When the GL_ARB_multitexture extension is supported, pushing and popping
       client vertex array state apples to all supported texture units, and the
       active client texture state.

ERRORS
