volmgt_inuse(3VOLMGT) Volume Management Library Functions volmgt_inuse(3VOLMGT)NAMEvolmgt_inuse - check whether or not Volume Management is managing a pathnameSYNOPSIScc [ flag ... ] file ... -lvolmgt [ library ... ] #include <volmgt.h> int volmgt_inuse(char *pathname);DESCRIPTIONvolmgt_inuse() checks whether Volume Management is managing the specified pathname.RETURN VALUESA non-zero value is returned if Volume Management is managing the specified pathname, otherwise 0 is returned.ERRORSThis 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.EXAMPLESExample 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 "); }ATTRIBUTESSee attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+SEE ALSOcc(1B), vold(1M), open(2), stat(2), errno(3C), volmgt_check(3VOLMGT), volmgt_running(3VOLMGT), attributes(5), volfs(7FS)NOTESThis 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.
