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       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-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.

NAME

       volmgt_ownspath - check volume management name space for path

SYNOPSIS

       cc [flag]... file... -lvolgmt [library]...
       #include <volmgt.h>

       int volmgt_ownspath(char *path);

PARAMETERS

       path    A string containing the 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       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-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.

       The  volmgt_ownspath() function checks to see if a given path is contained in the volume management name space. This is achieved by compar-
       ing the beginning of the supplied path name with the output from volmgt_root(3VOLMGT)

RETURN VALUES

       The return from this function is undefined.

EXAMPLES

       Example 1 Using volmgt_ownspath()

       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));
	      }
	 }
