.SH NAME
volmgt_root \- return the volume management root directory
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lvolmgt\fR [ \fIlibrary\fR ... ]
#include <volmgt.h>
\fBconst char *\fR\fBvolmgt_root\fR(\fBvoid\fR);
.fi

.SH DESCRIPTION
.sp
.LP
This function is obsolete. The management of removable media by the Volume
Management feature, including \fBvold\fR, has been replaced by software that
supports the Hardware Abstraction Layer (HAL). Programmatic support for HAL is
through the HAL APIs, which are documented on the HAL web site. See
\fBhal\fR(5). The return value of this function is undefined.
.sp
.LP
The \fBvolmgt_root()\fR function returns the current volume management root
directory, which by default is \fB/vol\fR but can be configured to be in a
different location.
.SH RETURN VALUES
.sp
.LP
The return from this function is undefined.
.SH ERRORS
.sp
.LP
This function may fail if an \fBopen()\fR of \fB/dev/volctl\fR fails.  If this
occurs a pointer to the default Volume Management root directory is returned.
.SH EXAMPLES
.LP
\fBExample 1 \fRFinding the Volume Management Root directory.
.sp
.LP
To find out where the volume management root directory is:

.sp
.in +2
.nf
if ((path = volmgt_root()) != NULL) {
        (void) printf("Volume Management root dir=%s\en", path);
} else {
        (void) printf("can't find Volume Management root dir\en");
}
