bsd_signal -- BSD version of signal(3)
Standard C Library (libc, -lc)
bsd_signal(int sig, void (*func)(int)))(int);
The bsd_signal() function provides a partially compatible interface for
programs written to historical system interfaces.
The previous action is returned on a successful call. Otherwise, SIG_ERR
is returned and the global variable errno is set to indicate the error.
The bsd_signal() function conforms to IEEE Std 1003.1-2004 (``POSIX.1'').
It was moved from X/Open to zbase in Issue 4 version 2. It first
appeared in NetBSD 8.
