notcurses_stop(3) notcurses_stop(3) NAME notcurses_stop - free up resources and restore initial terminal state SYNOPSIS #include <notcurses/notcurses.h> int notcurses_stop(struct notcurses* nc); DESCRIPTION notcurses_stop frees up any resources associated with the struct notcurses provided as nc, and attempts to restore the terminal to its state prior to calling notcurses_init(3). It also unregisters any signal handlers put into place by notcurses_init(3). nc must not be used following the call, and all references to ncplanes, cells, etc. are invalidated. Once the terminal has been reset, a summary of runtime and performance is printed, unless NCOPTION_SUPPRESS_BANNERS was provided to notcurses_init(3). The first step taken by notcurses_stop is a call to the internal function notcurses_stop_minimal. This is the same function called by the fatal sig- nal handlers installed in the absence of NCOPTION_NO_QUIT_SIGHANDLERS. This function: * Disables the Notcurses signal handlers * Emits the op terminfo capability, if supported * Emits the sgr0 terminfo capability, if supported * Emits the oc terminfo capability, if supported * Emits the rmcup terminfo capability, if supported (and if NCOPTION_NO_AL- TERNATE_SCREEN was not provided). * Emits the cnorm terminfo capability, if supported Respectively, these restore the default colorpair to its original value (op), turn off all text attributes (sgr0), restore the default palette (oc), exit the alternate screen (rmcup), and restore the cursor to its de- fault appearance (cnorm). It is legal to pass NULL to notcurses_stop. This is a no-op. NOTES Behavior is undefined if other threads are working with nc when or after this function is called. It is unlikely to be good. RETURN VALUES On success, 0 is returned. Otherwise, a negative value is returned.
