- check whether or not volume management is managing a pathname
cc [ flag... ] file... -lvolmgt [ library ... ] #include <volmgt.h> int volmgt_inuse(char *pathname);
This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by software that supports the Hardware Abstraction Layer (HAL).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.
volmgt_inuse() checks whether volume management is managing the specified pathname.
The return from this function is undefined.
Volume management is not running.
An interrupt signal was detected while checking for the supplied pathname for use.
See attributes(5) for descriptions of the following attributes:
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.
