curs_termattrs: baudrate, erasechar, has_ic, has_il, killchar, longname, termattrs, termname -- curses environment query routines

int baudrate(void); char erasechar(void); int has_ic(void); int has_il(void); char killchar(void); char *longname(void); chtype termattrs(void); char *termname(void);


The baudrate routine returns the output speed of the terminal. The number returned is in bits per second, for example 9600, and is an integer.

With the erasechar routine, the user's current erase character is returned.

The has_ic routine is true if the terminal has insert- and delete-character capabilities.

The has_il routine is true if the terminal has insert- and delete-line capabilities, or can simulate them using scrolling regions. This might be used to determine if it would be appropriate to turn on physical scrolling using scrollok.

With the killchar routine, the user's current line kill character is returned.

The longname routine returns a pointer to a static area containing a verbose description of the current terminal. The maximum length of a verbose description is 128 characters. It is defined only after the call to initscr or newterm. The area is overwritten by each call to newterm and is not restored by set_term, so the value should be saved between calls to newterm if longname is going to be used with multiple terminals.

If a given terminal doesn't support a video attribute that an application program is trying to use, curses may substitute a different video attribute for it. The termattrs function returns a logical OR of all video attributes supported by the terminal. This information is useful when a curses program needs complete control over the appearance of the screen.

The termname routine returns the value of the environment variable TERM (truncated to 14 characters).

Return values

longname and termname return NULL on error.

Routines that return an integer return ERR upon failure and an integer value other than ERR upon successful completion.

The header file ocurses.h automatically includes the header files stdio.h and unctrl.h.

Note that termattrs may be a macro.
