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This function is obsolete.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Volume Management feature, including vold, has been replaced by soft‐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.
