20.8. Displaying Signal Descriptions

Each signal has an associated printable description. These descriptions are listed in the array sys_siglist. For example, we can refer to sys_siglist[SIGPIPE] to get the description for SIGPIPE (broken pipe). However, rather than using the sys_siglist array directly, the strsignal() function is preferable.

#define _BSD_SOURCE
#include <signal.h>

extern const char *const sys_siglist[];

#define _GNU_SOURCE
#include <string.h>

char *strsignal(int sig);
