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       This function is obsolete.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       Volume  Management  feature, including vold, has been replaced by soft‐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 website. See hal(7). The return value of  this  function  is  unde‐
       fined.


       volmgt_inuse()  checks whether volume management is managing the speci‐
       fied pathname.

RETURN VALUES
       The return from this function is undefined.

ERRORS
       This routine can fail, returning 0, if a stat(2) of the supplied  path‐
       name  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  sup‐
                plied pathname for use.

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.
