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
