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
volmgt_inuse() checks whether Volume Management is managing the specified pathname.
RETURN VALUES
A non-zero value is returned if Volume Management is managing the specified pathname, otherwise 0 is returned.
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.
