22 .sp
23 .LP
24 This function is obsolete. The management of removable media by the Volume
25 Management feature, including \fBvold\fR, has been replaced by software that
26 supports the Hardware Abstraction Layer (HAL). Programmatic support for HAL is
27 through the HAL APIs, which are documented on the HAL web site. See
28 \fBhal\fR(5). The return value of this function is undefined.
29 .sp
30 .LP
31 \fBmedia_getid()\fR returns the \fIid\fR of a piece of media. Volume management
32 must be running. See \fBvolmgt_running\fR(3VOLMGT).

50 .sp
51 .LP
52 The following example first checks if volume management is running, then checks
53 the volume management name space for \fIpath\fR, and then returns the \fIid\fR
54 for the piece of media.

73 .LP
74 If a program using \fBmedia_getid()\fR does not check whether or not volume
75 management is running, then any \fBNULL\fR return value will be ambiguous, as
76 it could mean that either volume management does not have \fIpath\fR in its
77 name space, or volume management is not running.
