NAME
volmgt_release - release removable media device reservation
SYNOPSIS
cc [ flag ... ] file ... -lvolmgt [ library ... ] #include <volmgt.h> int volmgt_release(char *dev);
DESCRIPTION
The volmgt_release() routine releases the removable media device reservation specified as dev. See volmgt_acquire(3VOLMGT) for a descrip- tion of dev. If dev is reserved by the caller, volmgt_release() updates the internal device reservation database to indicate that the device is no longer reserved. If the requested device is reserved by another process, the release attempt fails and errno is set to 0.
RETURN VALUES
Upon successful completion, volmgt_release returns a non-zero value. Upon failure, 0 is returned.
ERRORS
On failure, volmgt_release() returns 0, and sets errno for one of the following conditions: EINVAL dev was invalid or missing. EBUSY dev was not reserved by the caller.
EXAMPLES
Example 1: Using volmgt_release() In the following example, Volume Management is running, and the first floppy drive is reserved, accessed and released. #include <volmgt.h> char *errp; if (!volmgt_acquire("floppy0", "FileMgr", 0, &errp, NULL)) { /* handle error case */ ... } /* floppy acquired - now access it */ if (!volmgt_release("floppy0")) { /* handle error case */ ... }
