Error codes

The following error codes can be retrieved by the glGetError function.

NameMeaning
GL_STACK_OVERFLOW

The function was called while the attribute stack was full.

GL_INVALID_OPERATION

The function was called between a call to glBegin and the corresponding call to glEnd.

Remarks

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 applying the logical OR operation to several of these constants. You can use the special mask GL_ALL_ATTRIB_BITS 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, you cannot save pixel pack and unpack state, render mode state, and select and feedback state.

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
