glPushClientAttrib — push and pop the client attribute stack
Specifies a mask that indicates which attributes to save. Values for
mask are listed below.
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.
is typically constructed by specifying the bitwise-or of several
of these constants together.
The special mask
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
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.
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.
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.
