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.
