STRSIGNAL

NAME

strsignal - return string describing signal

SYNOPSIS

#define _GNU_SOURCE


#include <string.h>

char *strsignal(int sig);

extern const char * const sys_siglist[];

DESCRIPTION

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

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

RETURN VALUE

The fBstrsignal()fP 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 fBNULLfP pointer may be returned instead for an invalid signal number.

CONFORMING TO

This function is not part of any standard, but may be found on Linux systems and some UNIX systems (such as Solaris).
