Values for +_param1 are listed below. +_names(PopClientAttrib) +.SH DESCRIPTION +_cmnd 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. +_param1(1) +is typically constructed by OR'ing several of these constants together. +The special mask +_const(CLIENT_ALL_ATTRIB_BITS) +can be used to save all stackable client state. +.P +The symbolic mask constants and their associated GL client state are as follows +(the second column lists which attributes are saved): +.P +_const(CLIENT_PIXEL_STORE_BIT) Pixel storage modes +.br +_const(CLIENT_VERTEX_ARRAY_BIT) Vertex arrays (and enables) +.P +_cmnd(PopClientAttrib) restores the values of the client-state variables +saved with the last _cmnd(PushClientAttrib). +Those not saved are left unchanged. +.P +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. +.P +Initially, the client attribute stack is empty. +.SH NOTES +_cmnd is available only if the GL version is 1.1 or greater. +.P +Not all values for GL client state can be saved on the attribute stack. +For example, select and feedback state cannot be saved. +.P +The depth of the attribute stack depends on the implementation, +but it must be at least 16. +.P +Use _cmnd(PushAttrib) and _cmnd(PopAttrib) 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 +_cmnd(PushClientAttrib) and _cmnd(PopClientAttrib). +.P +When the _arbstring(multitexture) extension is supported, pushing and +popping client vertex array state apples to all supported texture units, +and the active client texture state. +.SH ERRORS +_const(STACK_OVERFLOW) is generated if _cmnd(PushClientAttrib) is called while +the attribute stack is full. +.P +_const(STACK_UNDERFLOW) is generated if _cmnd(PopClientAttrib) is called while +the attribute stack is empty. +.SH ASSOCIATED GETS +_cmnd(Get) with argument _const(ATTRIB_STACK_DEPTH) +.br +_cmnd(Get) with argument _const(MAX_CLIENT_ATTRIB_STACK_DEPTH) +.SH SEE ALSO +_cmnd(ColorPointer), +_cmnd(DisableClientState), +_cmnd(EdgeFlagPointer), +_cmnd(EnableClientState), +_cmnd(Get), +_cmnd(GetError), +_cmnd(IndexPointer), +_cmnd(NormalPointer), +_cmnd(NewList), +_cmnd(PixelStore), +_cmnd(PushAttrib), +_cmnd(TexCoordPointer), +_cmnd(VertexPointer) |
