+.TH BUS_CREATE 3 BUS-%VERSION%
+.SH NAME
+bus_create - Create a new bus
+.SH SYNOPSIS
+.LP
+.nf
+#include <bus.h>
+.P
+int bus_create(const char *\fIfile\fP, int \fIflags\fP, char **\fIout_file\fP);
+.fi
+.SH DESCRIPTION
+The
+.BR bus_create ()
+function creates a bus with the asscoiated pathname specifed by the
+value of the parameter \fIfile\fP.  If \fIfile\fP is \fINULL\fP a random
+pathname is selected.  This pathname adheres to the convention set forth
+by
+.BR bus(5).
+.PP
+If \fIfile\fP is not \fINULL\fP the
+.BR bus_create ()
+function fails if the file already exists if \fIflags\fP contains
+\fIBUS_EXCL\fP.  Otherwise if \fIfile\fP is not \fINULL\fP, the
+.BR bus_create ()
+function does nothing if the file already exists.
+.PP
+If \fIflags\fP contains \fIBUS_INTR\fP, the function fails if it is
+interrupted.
+.PP
+Unless \fIout_file\fP is \fINULL\fP, the pathname of the bus should be
+stored in a new char array stored in \fI*out_file\fP.  The caller must
+free the allocated stored in \fI*out_file\fP.
+.SH RETURN VALUES
+Upon successful completion, the function returns 0.  Otherwise the
+function return -1 with \fIerrno\fP set to indicate the error.
+.SH ERRORS
+.TP
+.B ENOMEM
+The process cannot allocate more memory.
+.PP
+The
+.BR bus_create (3)
+function may also fail and set \fIerrno\fP to any
+of the errors specified for the routines
+.BR open (2)
+and
+.BR write (2).
