fglPushClientAttrib(3G)	       OpenGL Reference	       fglPushClientAttrib(3G)

NAME
     fglPushClientAttrib, fglPopClientAttrib - push and pop the client
     attribute stack

FORTRAN SPECIFICATION
     SUBROUTINE fglPushClientAttrib( INTEGER*4 mask )

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

FORTRAN SPECIFICATION
     SUBROUTINE fglPopClientAttrib( )

DESCRIPTION
     fglPushClientAttrib 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.  mask 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)

     fglPopClientAttrib restores the values of the client-state variables
     saved with the last fglPushClientAttrib.  Those not saved are left
     unchanged.

     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
     fglPushClientAttrib 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.

fglPushClientAttrib(3G)	       OpenGL Reference	       fglPushClientAttrib(3G)

     Use fglPushAttrib and fglPopAttrib 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 fglPushClientAttrib and fglPopClientAttrib.

ERRORS
     GL_STACK_OVERFLOW is generated if fglPushClientAttrib is called while the
     attribute stack is full.

     GL_STACK_UNDERFLOW is generated if fglPopClientAttrib is called while the
     attribute stack is empty.

ASSOCIATED GETS
     fglGet with argument GL_ATTRIB_STACK_DEPTH
     fglGet with argument GL_MAX_CLIENT_ATTRIB_STACK_DEPTH
