This means the physical - * scroll operation worked, and the refresh() code only had to do a - * partial repaint. - * - * $Id: view.c,v 1.52 2002/04/27 22:37:39 tom Exp $ - */ - -#include -#include -#include - -#include - -#if HAVE_TERMIOS_H -# include -#else -# include -#endif - -#if !defined(sun) || !HAVE_TERMIOS_H -# if HAVE_SYS_IOCTL_H -# include -# endif -#endif - -#define my_pair 1 - -/* This is needed to compile 'struct winsize' */ -#if NEED_PTEM_H -#include -#include -#endif - -static RETSIGTYPE finish(int sig) GCC_NORETURN; -static void show_all(const char *tag); - -#if defined(SIGWINCH) && defined(TIOCGWINSZ) && HAVE_RESIZETERM -#define CAN_RESIZE 1 -#else -#define CAN_RESIZE 0 -#endif - -#if CAN_RESIZE -static RETSIGTYPE adjust(int sig); -static int interrupted; -#endif - -static bool waiting = FALSE; -static int shift = 0; -static bool try_color = FALSE; - -static char *fname; -static NCURSES_CH_T **my_lines; -static NCURSES_CH_T **lptr; - -static void -usage(void) -{ - static const char *msg[] = - { - "Usage: view [options] file" - ,"" - ,"Options:" - ," -c use color if terminal supports it" - ," -i ignore INT, QUIT, TERM signals" - ," -n NUM specify maximum number of lines (default 1000)" -#if defined(KEY_RESIZE) - ," -r use old-style sigwinch handler rather than KEY_RESIZE" -#endif -#ifdef TRACE - ," -t trace screen updates" - ," -T NUM specify trace mask" -#endif - }; - size_t n; - for (n = 0; n < SIZEOF(msg); n++) - fprintf(stderr, "%s\n", msg[n]); - ExitProgram(EXIT_FAILURE); -} - -static int -ch_len(NCURSES_CH_T * src) -{ - int result = 0; -#if USE_WIDEC_SUPPORT -#endif - -#if USE_WIDEC_SUPPORT - while (getcchar(src++, NULL, NULL, NULL, NULL) > 0) - result++; -#else - while (*src++) - result++; -#endif - return result; -} - -/* - * Allocate a string into an array of chtype's.
