NAME

       strsignal - return string describing signal

SYNOPSIS

       #include <string.h>

       char *strsignal(int sig);

       extern const char * const sys_siglist[];

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       strsignal():
           Since glibc 2.10:
               _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
           Before glibc 2.10:
               _GNU_SOURCE

DESCRIPTION

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

       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

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