ttymsg - ttymsg utility function
System Utilities Library (libutil, -lutil)
#include <util.h>
char *
ttymsg(struct iovec *iov, int iovlen, const char *tty, int tmout);
The ttymsg() function is used by programs such as talkd(8), syslogd(8),
wall(1), etc., to display the contents of a uio structure on a terminal.
ttymsg() forks and finishes in the child if the write would block after
waiting up to tmout seconds.
ttymsg() returns a pointer to an error string on unexpected error; the
string is not newline-terminated. Various "normal" errors are ignored
(exclusive-use, lack of permission, etc.).
