.TH BUS_CREATE 1 BUS-%VERSION%
.SH NAME
bus_create - Create a new bus
.SH SYNOPSIS
#include <bus.h>
int bus_create(const char *file, int flags, char **out_file);
.SH DESCRIPTION
The \fIbus_create\fP function shall create a bus with the asscoiated pathname specifed by the value of the parameter \fIfile\fP. If the \fIfile\fP is \fINULL\fP, a random pathname shall be selected. This random pathname must adhere to the convention set forth by bus(5).
If \fIfile\fP is not \fINULL\fP, the \fIbus_create\fP function must fail if the file already exists if \fIflags\fP contains \fIBUS_EXCL\fP. Otherwise if \fIfile\fP is not \fINULL\fP, the \fIbus_create\fP function should do nothing if the file already exists.
If and only if \fIflags\fP contains \fIBUS_INTR\fP, the function shall fail if it is interrupted.
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 shall return 0. Otherwise the function shall return -1 and set \fIerrno\fP to indicate the error.
.SH ERRORS

.IR ENOMEM
The process cannot allocate more memory.
.SH
.BR
The \fIbus_create\fP() function may also fail and set \fIerrno\fP to any of the errors specified for the rutines open(2) and write(2).
