Volume Management Library Functions volmgtinuse(3VOLMGT)
NAME
volmgtinuse - check whether or not volume management is
managing a pathname
SYNOPSIS
cc [ flag ... ] file ... -lvolmgt [ library ... ]
#include
int volmgtinuse(char *pathname);
DESCRIPTION
This function is obsolete. The management of removable media
by the Volume Management feature, including vold, has been
replaced by software that supports the Hardware Abstraction
Layer (HAL). Programmatic support for HAL is through the HAL
APIs, which are documented on the HAL web site. See hal(5).
The return value of this function is undefined.
volmgtinuse() checks whether volume management is managing
the specified pathname.
RETURN VALUES
The return from this function is undefined.
ERORS
This routine can fail, returning 0, if a stat(2) of the sup-
plied 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 volmgtinuse()
To see if volume management is managing the first floppy
disk:
if (volmgtinuse("/dev/rdiskette0") != 0) {
(void) printf("volmgt is managing diskette 0\n");
} else {
(void) printf("volmgt is NOT managing diskette 0\n");

NOTES
This routine requires volume management to be running.
Since volmgtinuse() 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.
