NAME

6       glPushClientAttrib - push and pop the client attribute stack
7

C SPECIFICATION

9       void glPushClientAttrib(GLbitfield mask);
10

PARAMETERS

12       mask
13           Specifies a mask that indicates which attributes to save. Values
14           for mask are listed below.
15

C SPECIFICATION

17       void glPopClientAttrib(void);
18

DESCRIPTION

20       glPushClientAttrib takes one argument, a mask that indicates which
21       groups of client-state variables to save on the client attribute stack.
22       Symbolic constants are used to set bits in the mask.  mask is typically
23       constructed by specifying the bitwise-or of several of these constants
24       together. The special mask GL_CLIENT_ALL_ATTRIB_BITS can be used to
25       save all stackable client state.
26
27       The symbolic mask constants and their associated GL client state are as
28       follows (the second column lists which attributes are saved):
29
30       GL_CLIENT_PIXEL_STORE_BIT Pixel storage modes
31       GL_CLIENT_VERTEX_ARRAY_BIT Vertex arrays (and enables)
32
33       glPopClientAttrib() restores the values of the client-state variables
34       saved with the last glPushClientAttrib. Those not saved are left
35       unchanged.
36
37       It is an error to push attributes onto a full client attribute stack or
38       to pop attributes off an empty stack. In either case, the error flag is
39       set, and no other change is made to GL state.
40
41       Initially, the client attribute stack is empty.
42

NOTES

44       glPushClientAttrib is available only if the GL version is 1.1 or
45       greater.
46
47       Not all values for GL client state can be saved on the attribute stack.
48       For example, select and feedback state cannot be saved.
49
50       The depth of the attribute stack depends on the implementation, but it
51       must be at least 16.
52
53       Use glPushAttrib() and glPopAttrib() to push and restore state that is
54       kept on the server. Only pixel storage modes and vertex array state may
55       be pushed and popped with glPushClientAttrib and glPopClientAttrib().
56
57       For OpenGL versions 1.3 and greater, or when the ARB_multitexture
58       extension is supported, pushing and popping client vertex array state
59       applies to all supported texture units, and the active client texture
60       state.
61

ERRORS

63       GL_STACK_OVERFLOW is generated if glPushClientAttrib is called while
64       the attribute stack is full.
65
66       GL_STACK_UNDERFLOW is generated if glPopClientAttrib() is called while
67       the attribute stack is empty.
68

70       glGet() with argument GL_ATTRIB_STACK_DEPTH
71
72       glGet() with argument GL_MAX_CLIENT_ATTRIB_STACK_DEPTH
