sigignore() -- System Call (libc)

Tell the system to ignore a signal
#include <signal.h>
int sigignore (sigtype)
int sigtype;

sigignore() is  a member of  the sigset() family  of signal-handling system
calls.  It is equivalent to the system call

    sigset(sigtype, SIG_IGN);

This, in effect, tells the system to ignore all signals of type sigtype.

See the Lexicon entry for signal()  for a list of recognized signals.  Note
that signal SIGKILL cannot be ignored.

sigignore() returns  zero if  all went well.   If something went  wrong, it
returns -1 and sets errno to an appropriate value.
