Generates a printable representation of a character.
Curses Library (libcurses.a)
#include <curses.h> char *unctrl (chtype c);
The unctrl subroutine generates a character string that is a printable representation of c. If c is a control character, it is converted to the ^X notation. If c contains rendition information, the effect is undefined.
Upon successful completion, the unctrl subroutine returns the generated string. Otherwise, it returns a null pointer.
To display a printable representation of the newline character, enter:
char *new_line; int my_character; addstr ("Hit the enter key."); my_character=getch(); new_line=unctrl (my_character); printw (Newline=%s", new_line); refresh();
This prints, "newline=^J".
This subroutine is part of Base Operating System (BOS) Runtime.
The keyname (keyname, key_name Subroutine) subroutine.
