The sigabbrev_np returns the abbreviated signal name (e.g. "HUP" for SIGHUP) while sigdescr_np returns the string describing the error number (e.g "Hangup" for SIGHUP). Different than strsignal, sigdescr_np does not attempt to translate the return description and both functions return NULL for an invalid signal number. They should be used instead of sys_siglist or sys_sigabbrev and they are both thread and async-signal safe. They are added as GNU extensions on string.h header (same as strsignal). Checked on x86-64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, and s390x-linux-gnu. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com> |
