C++ (Cpp) blockSigs_ Examples

Example #1

File: lib.rdwr.c Project: Tambralinga/openlava

/* b_accept_()
 */
int
b_accept_(int s, struct sockaddr *addr, socklen_t *addrlen)
{
    sigset_t   oldMask;
    sigset_t   newMask;
    int        cc;

    blockSigs_(0, &newMask, &oldMask);

    cc = accept(s, addr, addrlen);
    sigprocmask(SIG_SETMASK, &oldMask, NULL);

    return (cc);

}  /* b_accept_() */
