media_getid(3VOLMGT)					Volume Management Library Functions				      media_getid(3VOLMGT)

NAME
       media_getid - return the id of a piece of media

SYNOPSIS
       cc [flag ...] file ...-lvolgmt [library ...]

       #include <volmgt.h>

       ulonglong_t media_getid(char *vol_path);

DESCRIPTION
       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-
       ware 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 hal(5). The return value of this function is undefined.

       media_getid() returns the id of a piece of media. Volume management must be running. See volmgt_running(3VOLMGT).

PARAMETERS
       vol_path    Path to the block or character special device.

RETURN VALUES
       The return from this function is undefined.

EXAMPLES
       Example 1 Using media_getid()

       The following example first checks if volume management is running, then checks the volume management name space for path, and then returns
       the id for the piece of media.

	 char *path;

	      ...

	 if (volmgt_running()) {
	      if (volmgt_ownspath(path)) {
		   (void) printf("id of %s is %lld
",
			path, media_getid(path));
	      }
	      }

       If a program using media_getid() does not check whether or not volume management is running, then any NULL return value will be	ambiguous,
       as it could mean that either volume management does not have path in its name space, or volume management is not running.
