STRSIGNAL(3)                  Linux Programmer's Manual                  STRSIGNAL(3)

NAME         top

       strsignal - return string describing signal

SYNOPSIS         top

       #define _GNU_SOURCE
       #include <string.h>

       char *strsignal(int sig);

       extern const char * const sys_siglist[];

DESCRIPTION         top

       The strsignal() function returns a string describing the signal number passed
       in the argument sig.  The string can only be used until the next call to
       strsignal().

       The array sys_siglist holds the signal description strings indexed by signal
       number.  The strsignal() function should be used if possible instead of this
       array.

RETURN VALUE         top

       The strsignal() function returns the appropriate description string, or an
       unknown signal message if the signal number is invalid.  On some systems (but
       not on Linux), a NULL pointer may be returned instead for an invalid signal
       number.

CONFORMING TO         top

       POSIX.1-2008.  Present on Solaris and the BSDs.
