# glPushClientAttrib

## 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`
