curs_termattrs(3X) Library calls curs_termattrs(3X) NAME baudrate, erasechar, erasewchar, has_ic, has_il, killchar, killwchar, longname, term_attrs, termattrs, termname - get and set terminal at- tributes with curses SYNOPSIS #include <curses.h> int baudrate(void); char erasechar(void); int erasewchar(wchar_t * wc); bool has_ic(void); bool has_il(void); char killchar(void); int killwchar(wchar_t * wc); char * longname(void); attr_t term_attrs(void); chtype termattrs(void); char * termname(void); DESCRIPTION baudrate baudrate returns the line speed of the terminal, an integer value mea- sured in bits per second, for example 9600. erasechar, erasewchar erasechar returns the terminal's erase character. erasewchar stores the erase character in the location referenced by wc. If no erase character has been defined, it fails and the location ref- erenced by wc is not changed. has_ic, has_il has_ic returns TRUE if the terminal has insert- and delete-character capabilities. has_il returns TRUE if the terminal has insert- and delete-line capa- bilities, or can simulate them using scrolling regions. It might be used to determine whether it would be appropriate to use scrollok(3X) to turn on scrolling. killchar, killwchar killchar returns the terminal's line kill character. killwchar stores the line-kill character in the location referenced by wc. If no line-kill character has been defined, it fails and the loca- tion referenced by wc is not changed. longname longname returns a pointer to static storage containing a verbose de- scription of the terminal being managed by curses. The maximum length of a verbose description is 128 characters. The storage is populated only after initscr(3X) or newterm(3X) is called. This storage is over- written by each call to newterm and not restored by set_term(3X), so its contents should be saved between calls to initscr or newterm if longname is to be used with multiple terminals. termattrs, term_attrs If a given terminal does not support a video attribute that an applica- tion program is trying to use, curses may substitute a different video attribute for it. termattrs and term_attrs return a logical "or" of all video attributes supported by the terminal using A_ and WA_ con- stants respectively. This information is useful when a curses program needs complete control over the appearance of the screen. termname termname returns the terminal name used by setupterm(3X). RETURN VALUE longname and termname return NULL on error. Functions that return an integer return ERR upon failure and OK upon success. NOTES erasewchar, killwchar, and term_attrs are part of ncurses's wide-char- acter API, and are not available in its non-wide-character configura- tion. termattrs may be implemented as a macro. PORTABILITY X/Open Curses Issue 4 describes these functions. SVr4 describes a successful return value only as "an integer value other than ERR". Most versions of curses truncate the string returned by termname to 14 characters. HISTORY 4BSD (1980) introduced longname. SVr2 (1984) added baudrate, erasechar, killchar, has_ic, and has_il. SVr3 (1987) supplied termname. Later that year, SVr3.1 brought termattrs. X/Open Curses Issue 4 (1995) specified erasewchar, killwchar, and term_attrs.
