Package: flex Version: 2.5.37 Maintainer: Manoj Srivastava <[email protected]> Description: Section 11 Multiple Input Buffer function enhancement
void yypush_buffer_state( YY_BUFFER_STATE buffer ) void yypop_buffer_state ( ) Should have a YY_BUFFER_STATE return argument, that is YY_BUFFER_STATE yypush_buffer_state( YY_BUFFER_STATE buffer ); return &uffer YY_BUFFER_STATE yypop_buffer_state ( ); return &YY_BUFFER_STATE of poped state The argument is: 1: yypush_buffer_state creates a stack and stores a state onto the stack. 2: yypop_buffer_state pops the stack but does not return an address to the state stacked. 3: A user attempting to use yy_delete_buffer(YY_BUFFER_STATE) must maintain an external stack of states. At the same time, the flex runtime maintains a stack of states. It would seem to be better that the state information poped is returned to remove the requirement for a user stack. And, as if an 'and' were necessary, the user could do: yy_delete_buffer(yypop_buffer_state()); to perform the required delete.
