SYNOPSIS
#include
<util.h>
const char *
getfsspecname(char
*buf, size_t
buflen, const char
*spec);
DESCRIPTION
Thegetfsspecname()
function translates an fs_spec field in the
spec argument of the form “NAME=wedgename”
to the underlying dk(4) device node, and places the resulting pathname in
buf up to len buflen.
If the spec argument starts with “ROOT.”, a path in the form “/dev/[root_device][suffix]” is copied to buf, where [root_device] is the value of the “kern.root_device” sysctl and [suffix] is the characters following “ROOT.” in the spec argument.
If the spec argument is not of the form “NAME=wedgename” and it doesn't start with “ROOT.”, spec is copied to buf and returned.
RETURN VALUES
On success the absolute pathname of the underlying wedge device is
returned, or the original spec argument. On failure
NULL is returned and buf
contains the reason for the error.
