21 This function is obsolete. The management of removable media by the Volume
22 Management feature, including \fBvold\fR, has been replaced by software that
23 supports the Hardware Abstraction Layer (HAL). Programmatic support for HAL is
24 through the HAL APIs, which are documented on the HAL web site. See
25 \fBhal\fR(5). The return value of this function is undefined.

33 The return from this function is undefined.
37 This routine can fail, returning \fB0\fR, if a \fBstat\fR(2) of the supplied
38 \fIpathname\fR or an \fBopen\fR(2) of \fB/dev/volctl\fR fails, or if any of the

69 if (volmgt_inuse("/dev/rdiskette0") != 0) {
70 (void) printf("volmgt is managing diskette 0\en");

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