NAME         top

       strsignal - return string describing signal

SYNOPSIS         top

       #include <string.h>

       char *strsignal(int sig);

       extern const char * const sys_siglist[];

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

           Since glibc 2.10:
               _POSIX_C_SOURCE >= 200809L
           Before glibc 2.10:

DESCRIPTION         top

       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         top

       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), NULL may instead be returned for an
       invalid signal number.
