command. +Those not saved are left unchanged. +.P +It is an error to push attributes onto a full 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 attribute stack is empty. +.SH NOTES +Not all values for GL state can be saved on the attribute stack. +For example, +render mode state, +and select and feedback state cannot be saved. +Client state must be saved with +_cmnd(PushClientAttrib). +.P +The depth of the attribute stack depends on the implementation, +but it must be at least 16. +.P +When the _arbstring(multitexture) extension is supported, pushing and +popping texture state applies to all supported texture units. +.SH ERRORS +_const(STACK_OVERFLOW) is generated if _cmnd(PushAttrib) is
