The psignal() and psiginfo() functions produce messages on the standard error output describing a signal. The sig argument is a signal that may have been passed as the first argument to a signal handler. The pinfo argument is a pointer to a siginfo structure that may have been passed as the second argument to an enhanced signal handler. See sigaction(2). The argument string s is printed first, followed by a colon and a blank, followed by the message and a NEWLINE character.

If the application is linked with -lintl, then messages printed from these functions are in the native language specified by the LC_MESSAGES locale category. See setlocale(3C).
