In cbreak mode, + characters typed by the user are made available immediately, and + erase/kill character processing is not performed. In nocbreak + mode, typed characters are buffered until a newline or carriage + return. Interrupt and flow control characters are unaffected by + this mode. PDCurses always starts in cbreak mode. + + echo() and noecho() control whether typed characters are echoed + by the input routine. Initially, input characters are echoed. + Subsequent calls to echo() and noecho() do not flush type-ahead. + + halfdelay() is similar to cbreak(), but allows for a time limit + to be specified, in tenths of a second. This causes getch() to + block for that period before returning ERR if no key has been + received. tenths must be between 1 and 255. + + keypad() controls whether getch() returns function/special keys + as single key codes (e.g., the left arrow key as KEY_LEFT). Per + X/Open, the default for keypad mode is OFF. You'll probably want + it on. With keypad mode off, if a special key is pressed, + getch() does nothing or returns ERR. + + nodelay() controls whether wgetch() is a non-blocking call. If + the option is enabled, and no input is ready, wgetch() will + return ERR. If disabled, wgetch() will hang until input is + ready. + + nl() enables the translation of a carriage return into a newline + on input. nonl() disables this. Initially, the translation does + occur. + + raw() and noraw() toggle raw mode. Raw mode is similar to cbreak + mode, in that characters typed are immediately passed through to + the user program. The difference is that in raw mode, the INTR, + QUIT, SUSP, and STOP characters are passed through without being + interpreted, and without generating a signal. + + In PDCurses, the meta() function sets raw mode on or off. + + timeout() and wtimeout() set blocking or non-blocking reads for + the specified window. The delay is measured in milliseconds. If + it's negative, a blocking read is used; if zero, then non- + blocking reads are done -- if no input is waiting, ERR is + returned immediately. If the delay is positive, the read blocks + for the delay period; if the period expires, ERR is returned. + + intrflush(), notimeout(), noqiflush(), qiflush() and typeahead() + do nothing in PDCurses, but are included for compatibility with + other curses implementations. + + crmode() and nocrmode() are archaic equivalents to cbreak() and + nocbreak(), respectively. + + Return Value: + All functions return OK on success and ERR on error. + + Portability X/Open BSD SYS V + cbreak Y Y Y + nocbreak Y Y Y + echo Y Y Y + noecho Y Y Y + halfdelay Y - Y + intrflush Y - Y + keypad Y - Y + meta Y - Y + nl Y Y Y + nonl Y Y Y + nodelay Y - Y + notimeout Y - Y + raw Y Y Y + noraw Y Y Y + noqiflush Y - Y + qiflush Y - Y + timeout Y - Y + wtimeout Y - Y + typeahead Y - Y + crmode - + nocrmode - + +**man-end****************************************************************/ + +int cbreak(void) +{ + PDC_LOG(("cbreak() - called\n")); + + SP->cbreak = TRUE; + + return OK; +} + +int nocbreak(void) +{ + PDC_LOG(("nocbreak() - called\n")); + + SP->cbreak = FALSE; + SP->delaytenths = 0; + + return OK; +} + +int echo(void) +{ + PDC_LOG(("echo() - called\n")); + + SP->echo = TRUE; + + return OK; +} + +int noecho(void) +{ + PDC_LOG(("noecho() - called\n")); + + SP->echo = FALSE; + + return OK; +} + +int halfdelay(int tenths) +{ + PDC_LOG(("halfdelay() - called\n")); + + if (tenths < 1 || tenths > 255) + return ERR; + + SP->delaytenths = tenths; + + return OK; +} + +int intrflush(WINDOW *win, bool bf) +{ + PDC_LOG(("intrflush() - called\n")); + + return OK; +} + +int keypad(WINDOW *win, bool bf) +{ + PDC_LOG(("keypad() - called\n")); + + if (!win) + return ERR; + + win->_use_keypad = bf; + + return OK; +} + +int meta(WINDOW *win, bool bf) +{ + PDC_LOG(("meta() - called\n")); + + SP->raw_inp = bf; + + return OK; +} + +int nl(void) +{ + PDC_LOG(("nl() - called\n")); + + SP->autocr = TRUE; + + return OK; +} + +int nonl(void) +{ + PDC_LOG(("nonl() - called\n")); + + SP->autocr = FALSE; + + return OK; +} + +int nodelay(WINDOW *win, bool flag) +{ + PDC_LOG(("nodelay() - called\n")); + + if (!win) + return ERR; + + win->_nodelay = flag; + + return OK; +} + +int notimeout(WINDOW *win, bool flag) +{ + PDC_LOG(("notimeout() - called\n")); + + return OK; +} + +int raw(void) +{ + PDC_LOG(("raw() - called\n")); + + PDC_set_keyboard_binary(TRUE); + SP->raw_inp = TRUE; + + return OK; +} + +int noraw(void) +{ + PDC_LOG(("noraw() - called\n")); + + PDC_set_keyboard_binary(FALSE); + SP->raw_inp = FALSE; + + return OK; +} + +void noqiflush(void) +{ + PDC_LOG(("noqiflush() - called\n")); +} + +void qiflush(void) +{ + PDC_LOG(("qiflush() - called\n")); +} + +int typeahead(int fildes) +{ + PDC_LOG(("typeahead() - called\n")); + + return OK; +} + +void wtimeout(WINDOW *win, int delay) +{ + PDC_LOG(("wtimeout() - called\n")); + + if (!win) + return; + + if (delay < 0) + { + /* This causes a blocking read on the window, so turn on delay + mode */ + + win->_nodelay = FALSE; + win->_delayms = 0; + } + else if (!delay) + { + /* This causes a non-blocking read on the window, so turn off + delay mode */ + + win->_nodelay = TRUE; + win->_delayms = 0; + } + else + { + /* This causes the read on the window to delay for the number of + milliseconds.
