TICKIT_TER...E_SIGWINCH(3) Library Functions Manual TICKIT_TER...E_SIGWINCH(3) NAME tickit_term_observe_sigwinch - react to the SIGWINCH signal SYNOPSIS #include <tickit.h> void tickit_term_observe_sigwinch(TickitTerm *tt, bool observe); Link with -ltickit. DESCRIPTION tickit_term_observe_sigwinch() controls a setting on the TickitTerm in- stance that allows it to be informed when the process receives a SIG- WINCH signal, meaning that the controlling terminal may have changed size. When this flag is enabled on at least one terminal instance, a handler for the SIGWINCH signal is automatically installed by libtickit itself. On receipt of the signal the handler will mark a flag on any TickitTerm instance that is observing it to indicate that the window may have changed size. The next time these instances invoke any of several in- put-related functions (listed below), this flag will cause the function to first perform the actions of tickit_term_refresh_size(3). This de- ferred handling ensures that the TICKIT_EV_RESIZE event is only invoked at a time when the application is expecting input events, and not asyn- chronously during the signal handler itself. Note that use of this ability requires giving control of the process- wide SIGWINCH signal to the libtickit library. If this is not suitable, the process should arrange to invoke tickit_term_refresh_size() at an appropriate time by some other mechanism.
