- release removable media device reservation
cc [ flag ... ] file ... -lvolmgt [ library ... ] #include <volmgt.h> int volmgt_release(char *dev);
This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by software that supports the Hardware Abstraction Layer (HAL).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.
The volmgt_release() routine releases the removable media device reservation specified as dev. See volmgt_acquire(3VOLMGT) for a description of dev.
If dev is reserved by the caller, volmgt_release() updates the internal device reservation database to indicate that the device is no longer reserved. If the requested device is reserved by another process, the release attempt fails and errno is set to 0.
The return from this function is undefined.
On failure, volmgt_release() returns 0, and sets errno for one of the following conditions:
dev was invalid or missing.
dev was not reserved by the caller.
