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

NAME

       volmgt_inuse - check whether or not volume management is managing a pathname

SYNOPSIS

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

       int volmgt_inuse(char *pathname);

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       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-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

       volmgt_inuse() checks whether volume management is managing the specified pathname.

RETURN VALUES

       The return from this function is undefined.

ERRORS

       This routine can fail, returning 0, if a stat(2) of the supplied pathname or 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 checking for the supplied pathname for use.

EXAMPLES

       Example 1 Using volmgt_inuse()

       To see if volume management is managing the first floppy disk:

	 if (volmgt_inuse("/dev/rdiskette0") != 0) {
		 (void) printf("volmgt is managing diskette 0
");
	 } else {
		 (void) printf("volmgt is NOT managing diskette 0
");
	 }

NOTES

       This routine requires volume management to be running.

       Since volmgt_inuse() returns 0 for two different cases (both when a volume is not in use, and when an error occurs), it is up to  the  user
       to to check errno to differentiate the two, and to ensure that volume management is running.

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

NAME

       volmgt_check - have Volume Management check for media

SYNOPSIS

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

       int volmgt_check(char *pathname);

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       This  function  is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft-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

       This routine asks volume Management to check the specified pathname and determine if new media has been inserted in that drive.

       If a null pointer is passed in, then Volume Management will check each device it is managing that can be checked.

       If new media is found, volmgt_check() tells volume management to initiate appropriate actions.

RETURN VALUES

       The return from this function is undefined.

ERRORS

       This routine can fail, returning 0, if a stat(2) or open(2) of the supplied pathname fails, or if any of the following is true:

       ENXIO	volume management is not running.

       EINTR	An interrupt signal was detected while checking for media.

EXAMPLES

       Example 1 Checking If Any New Media Is Inserted

       To check if any drive managed by volume management has any new media inserted in it:

	 if (volmgt_check(NULL)) {
		 (void) printf("Volume management found media
");
	 }

       This would also request volume management to take whatever action was appropriate for the new media.

       check errno to differentiate the two, and to ensure that volume management is running.
