GLPUSHCLIENTATTRIB(3G)			  OpenGL Manual 		   GLPUSHCLIENTATTRIB(3G)

NAME
       glPushClientAttrib - push and pop the client attribute stack

C SPECIFICATION
       void glPushClientAttrib(GLbitfield mask);

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

C SPECIFICATION
       void glPopClientAttrib(void);

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.  mask is typically constructed by specifying the bitwise-or of 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 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
       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 that is kept on the server.
       Only pixel storage modes and vertex array state may be pushed and popped with
       glPushClientAttrib and glPopClientAttrib().

       For OpenGL versions 1.3 and greater, or when the ARB_multitexture extension is supported,
       pushing and popping client vertex array state applies to all supported texture units, and
       the active client texture state.

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

       GL_STACK_UNDERFLOW is generated if glPopClientAttrib() is called while the attribute stack
       is empty.

ASSOCIATED GETS
       glGet() with argument GL_ATTRIB_STACK_DEPTH

       glGet() with argument GL_MAX_CLIENT_ATTRIB_STACK_DEPTH
