sigemptyset(sigset_t *set);
int
sigfillset(sigset_t *set);
int
sigaddset(sigset_t *set, int signo);
int
sigdelset(sigset_t *set, int signo);
int
sigismember(sigset_t *set, int signo);
The sigemptyset() function initializes a signal set to be empty.
The sigfillset() function initializes a signal set to contain all signals.
The sigaddset() function adds the specified signal signo to the signal set.
The sigdelset() function deletes the specified signal signo from the signal set.
The sigismember() function returns whether a specified signal signo is contained in the signal set.
sigemptyset() and sigfillset() are provided as macros, but actual functions are available if their names are undefined (with #undef name).
