VOLMGT_RUNNING(3VOLMGT)				       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       This  function  is  obsolete.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       Volume Management feature, including vold, has been replaced  by	 soft‐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 Vol‐
		ume 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\n");
	 } else {
		 (void) printf("Volume Management is NOT running\n");
	 }

       library routines to work.
