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 

     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     This function is obsolete.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     by  the  Volume Management feature, including vold, has been
     replaced by software that supports the Hardware  Abstraction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  Manage-
     ment (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\n");
       } else {
               (void) printf("Volume Management is NOT running\n");
       }
