.SH NAME
volmgt_inuse \- check whether or not volume management is managing a pathname
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lvolmgt\fR [ \fIlibrary\fR ... ]
#include <volmgt.h>

\fBint\fR \fBvolmgt_inuse\fR(\fBchar *\fR\fIpathname\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This function is obsolete.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Management feature, including \fBvold\fR, has been replaced by software that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(7). The return value of this function is undefined.
.sp
.LP
\fBvolmgt_inuse()\fR checks whether volume management is managing the specified
\fIpathname\fR.
.SH RETURN VALUES
.sp
.LP
The return from this function is undefined.
.SH ERRORS
.sp
.LP
This routine can fail, returning \fB0\fR, if a \fBstat\fR(2) of the supplied
\fIpathname\fR or an \fBopen\fR(2) of \fB/dev/volctl\fR fails, or if any of the
following is true:
.sp
.ne 2
.na
\fB\fBENXIO\fR\fR
.ad
.RS 9n
Volume management is not running.
.RE

.sp
.ne 2
.na
\fB\fBEINTR\fR\fR
.ad
.RS 9n
An interrupt signal was detected while checking for the supplied \fIpathname\fR
for use.
.RE

.SH EXAMPLES
.LP
\fBExample 1 \fRUsing \fBvolmgt_inuse()\fR
.sp
.LP
To see if volume management is managing the first floppy disk:

.sp
.in +2
.nf
if (volmgt_inuse("/dev/rdiskette0") != 0) {
        (void) printf("volmgt is managing diskette 0\en");
} else {
        (void) printf("volmgt is NOT managing diskette 0\en");
}
.fi

.SH NOTES
.sp
.LP
This routine requires volume management to be running.
.sp
.LP
Since \fBvolmgt_inuse()\fR returns \fB0\fR for two different cases (both when a
volume is not in use, and when an error occurs), it is up to the user to to
check \fBerrno\fR to differentiate the two, and to ensure that volume
management is running.
