void glPopAttrib(
void
);
The glPushAttrib function takes one argument, a mask that indicates which groups of state variables to save on the attribute stack. Symbolic constants are used to set bits in the mask. The mask parameter is typically constructed by ORing several of these constants together. The special mask GL_ALL_ATTRIB_BITS can be used to save all stackable states.
The glPopAttrib function restores the values of the state variables saved with the last glPushAttrib command. Those not saved are left unchanged.
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 the OpenGL state.
Initially, the attribute stack is empty.
Not all values for the OpenGL state can be saved on the attribute stack. For example, pixel pack and unpack state, render mode state, and select and feedback state cannot be saved.
The depth of the attribute stack depends on the implementation, but it must be at least 16.
The following functions retrieve information related to glPushAttrib and glPopAttrib:
glGet with argument GL_ATTRIB_STACK_DEPTH
glGet with argument GL_MAX_ATTRIB_STACK_DEPTH
The following are the error codes generated and their conditions.
| Error Code | Condition |
|---|---|
| GL_STACK_OVERFLOW | glPushAttrib was called while the attribute stack was full. |
| GL_STACK_UNDERFLOW | glPopAttrib was called while the attribute stack was empty. |
| GL_INVALID_OPERATION | glPushAttrib was called between a call to glBegin and the corresponding call to glEnd. |
