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

NAME

       volmgt_root - return the volume management root directory

SYNOPSIS

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

       const char *volmgt_root(void);

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       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-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_root() function returns the current volume management root directory, which by default is /vol but can be configured to be in a
       different location.

RETURN VALUES

       The return from this function is undefined.

ERRORS

       This function may fail if an open() of /dev/volctl fails.  If this occurs a pointer to the default  Volume  Management  root  directory	is
       returned.

EXAMPLES

       Example 1 Finding the Volume Management Root directory.

       To find out where the volume management root directory is:

	 if ((path = volmgt_root()) != NULL) {
		 (void) printf("Volume Management root dir=%s
", path);
	 } else {
		 (void) printf("can't find Volume Management root dir
");
	 }

FILES

       /dev    default location for the volume management root directory

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

NAME

       volmgt_symname, volmgt_symdev - convert between Volume Management symbolic names, and the devices that correspond to them

SYNOPSIS

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

       char *volmgt_symname(char *pathname);

       char *volmgt_symdev(char *symname);

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       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-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

       These  two  routines  compliment  each other, translating between Volume Management's symbolic name for a device, called a symname, and the
       /dev pathname for that same device.

       volmgt_symname() converts a supplied /dev pathname to a symname, Volume Management's idea of that device's symbolic name.

       volmgt_symdev() does the opposite conversion, converting between a symname, Volume Management's idea of a device's symbolic name for a vol-
       ume, to the /dev pathname for that device.

RETURN VALUES

       The return from this function is undefined.

ERRORS

       volmgt_symname()  can  fail,  returning a null string pointer, if a stat(2) of the supplied pathname fails, or if an open(2) of /dev/volctl
       fails, or if any of the following is true:

       ENXIO	Volume Management is not running.

       EINTR	An interrupt signal was detected while trying to convert the supplied pathname to a symname.

       volmgt_symdev() can fail if an open(2) of /dev/volctl fails, or if any of the following is true:

       ENXIO	Volume Management is not running.

       EINTR	An interrupt signal was detected while trying to convert the supplied symname to a /dev pathname.

EXAMPLES

       Example 1 Testing Floppies

       The following tests how many floppies Volume Management currently sees in floppy drives (up to 10):

	 for (i=0; i < 10; i++) {
		 (void) sprintf(path, "floppy%d", i);
		 if (volmgt_symdev(path) != NULL) {
			 (void) printf("volume %s is in drive %d
",
			     path, i);
		 }
	 }

       Example 2 Finding The Symbolic Name

       This code finds out what symbolic name (if any) Volume Management has for /dev/rdsk/c0t6d0s2:

	 if ((nm = volmgt_symname("/dev/rdsk/c0t6d0s2")) == NULL) {
		 (void) printf("path not managed
");
	 } else {
		 (void) printf("path managed as %s
", nm);
	 }
