Name
strsignal — return string describing signal
Synopsis
char
*strsignal( |
int |
sig) ; |
DESCRIPTION
The 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 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
This function is not part of any standard, but aside from
Linux, it can be found on Solaris and the BSDs.
