NAME

     ttymsg -- ttymsg utility function


LIBRARY

     System Utilities Library (libutil, -lutil)


SYNOPSIS

     #include <util.h>

     char *
     ttymsg(struct iovec *iov, int iovlen, const char *tty, int tmout);


DESCRIPTION

     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.


RETURN VALUES

     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.).
