int audit_request_signal_info(int fd);
audit_request_signal_info requests that the kernel send information about the sender of a signal to the audit daemon. The sinal info structure is as follows:
struct audit_sig_info {
uid_t uid;
pid_t pid;
char ctx[0];
};
This function is likely to be used only by audit daemons and shouldn't be called by any other kind of program.
The return value is <= 0 on error, otherwise it is the netlink sequence id number. This function can have any error that sendto would encounter.
