Volume Management Library Functions volmgtcheck(3VOLMGT)
NAME
volmgtcheck - have Volume Management check for media
SYNOPSIS
cc [ flag ... ] file ... -lvolmgt [ library ... ]
#include
int volmgtcheck(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This function is obsolete.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by the Volume Management feature, including vold, has been
replaced by software that supports the Hardware Abstraction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.
This routine asks volume Management to check the specified
pathname and determine if new media has been inserted in
that drive.
If a null pointer is passed in, then Volume Management will
check each device it is managing that can be checked.
If new media is found, volmgtcheck() tells volume manage-
ment to initiate appropriate actions.
RETURN VALUES
The return from this function is undefined.
ERORS
This routine can fail, returning 0, if a stat(2) or open(2)
of the supplied pathname fails, or if any of the following
is true:
ENXIO volume management is not running.
EINTR An interrupt signal was detected while checking for
media.
EXAMPLES
Example 1 Checking If Any New Media Is Inserted

Volume Management Library Functions volmgtcheck(3VOLMGT)
To check if any drive managed by volume management has any
new media inserted in it:
if (volmgtcheck(NUL)) {
(void) printf("Volume management found media\n");
}
This would also request volume management to take whatever
action was appropriate for the new media.

NOTES
Since volmgtcheck() returns 0 for two different cases
(both when no media is found, 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.
