strsignal

strsignal - return string describing signal

#define _GNU_SOURCE

#include <string.h>
 I char *strsignal(int  sig );
 I extern const char * const  sys_siglist [];

The R 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 R strsignal ().

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

The R 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.

This function is not part of any standard, but aside from Linux, it can be found on Solaris and the BSDs.
