volmgt_running

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       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-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