+.TH BUS_WRITE 3 BUS
+.SH NAME
+bus_write, bus_write_timed - Broadcast a message a bus
+.SH SYNOPSIS
+.LP
+.nf
+#include <bus.h>
+.P
+int bus_write(const bus_t *\fIbus\fP, const char *\fImessage\fP, int \fIflags\fP);
+int bus_write_timed(const bus_t *\fIbus\fP, const char *\fImessage\fP,
+                    const struct timespec *\fItimeout\fP, clockid_t \fIclockid\fP);
+.fi
+.SH DESCRIPTION
+The
+.BR bus_write ()
+function broadcasts a message on the bus whose information is stored in
+\fIbus\fP.  The message read by the function is stored in the parameter
+\fImessage\fP.  It may not exceeed 2048 bytes, including NULL termination.
+.PP
+The
+.BR bus_write ()
+function shall fail, and set \fIerrno\fP to \fIEAGAIN\fP, if the call
+would suspend the process and (\fIflags\fP &BUS_NOWAIT).
+.PP
+The
+.BR bus_write_timed ()
+function behaves like
+.BR bus_write (),
+except if it is not able to write the \fImessage\fP within the specified
+time, it will fail and set \fIerrno\fP to \fBEAGAIN\fP.  The time is
+specified as an absolute time using the parameter \fItimeout\fP.  The
+behaviour is unspecified if \fItimeout\fP is \fINULL\fP. \fItimeout\fP
+is measured with the clock whose ID is specified by the \fIclockid\fP
+parameter.  This clock must be a predicitable clock.
+.SH RETURN VALUES
+Upon successful completion, these functions returns 0.  Otherwise the
+function returns -1 and sets \fIerrno\fP to indicate the error.
+.SH ERRORS
+The
+.BR bus_write (3)
+function may fail and set \fIerrno\fP to any of the errors specified for
+.BR semop (3).
+The
+.BR bus_write_timed (3)
+function may also set \fIerrno\fP to any of the errors specified for
+.BR clock_gettime (3).
