#include <string.h>

strsignal(int sig);

The strsignal() function returns a pointer to the string describing the signal sig.

The array pointed to is not to be modified by the program, but may be overwritten by subsequent calls to strsignal().

intro(2), psignal(3), setlocale(3)

The strsignal() function conforms to IEEE Std 1003.1-2008 (“POSIX.1”).

The strsignal() function first appeared in AT&T System V Release 4 UNIX and was reimplemented for NetBSD 1.0.

On systems other than OpenBSD, the LC_MESSAGES locale(1) category can cause different strings to be returned instead of the normal signal descriptions; see CAVEATS in setlocale(3) for details.
