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.).
