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

NAME

       volmgt_running - return whether or not volume management is running

SYNOPSIS

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

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       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-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

       volmgt_running() tells whether or not Volume Management is running.

RETURN VALUES

       volmgt_running() always returns 0 indicating Volume Management (as implemented by vold) is not running.

ERRORS

       volmgt_running() will fail, returning 0, if a stat(2) or 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 checking to see if Volume Management was running.

EXAMPLES

       Example 1 Using volmgt_running()

       To see if Volume Management is running:

	 if (volmgt_running() != 0) {
		 (void) printf("Volume Management is running
");
	 } else {
		 (void) printf("Volume Management is NOT running
");
	 }

NOTES

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       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-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

NOTES

       This function returns the default root directory location even when volume management is not running.
