OPENDEV(3)                OpenBSD Programmer's Manual               OPENDEV(3)

NAME
     opendev - short form device open routine



SYNOPSIS
     #include <util.h>

     int
     opendev(char *path, int oflags, int dflags, char **realpath);

DESCRIPTION
     The opendev() function opens a device using the ``short form'' name.
     This is typically ``sd0'' or ``sd0c'', for instance, which will be ex-
     panded to /dev/rsd0c on most architectures.

     The oflags are the same as the flags passed to open(2).

     The dflags are specified by OR'ing the following values:

           OPENDEV_PART    attempt to open the raw partition during expansion
           OPENDEV_DRCT    attempt to open the device itself during expansion

     If realpath is not NULL, it is modified to point at the fully expanded
     device name.

RETURN VALUES
     The opendev() return value and errors are the same as the return value
     and errors of open(2).

SEE ALSO
     open(2)

HISTORY
     The opendev() function first appeared in OpenBSD 1.2.
