POSIX states: The string pointed to shall not be modified by the application, but may be overwritten by a subsequent call to strsignal() or setlocale(). The only reason that the return value is not const char * is because strsignal predates C89 const. But applications should treat it as const char anyways. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
