All Implemented Interfaces:

AutoCloseable

Deprecated.

This function does nothing, and always returns 0. Be sure to build with thread support to get basic thread safety.

@Properties(inherit=avcodec.class)
public class Cb_PointerPointer_int
extends FunctionPointer

Register a user provided lock manager supporting the operations specified by AVLockOp. The "mutex" argument to the function points to a (void *) where the lockmgr should store/get a pointer to a user allocated mutex. It is NULL upon AV_LOCK_CREATE and equal to the value left by the last call for all other ops. If the lock manager is unable to perform the op then it should leave the mutex in the same state as when it was called and return a non-zero value. However, when called with AV_LOCK_DESTROY the mutex will always be assumed to have been successfully destroyed. If av_lockmgr_register succeeds it will return a non-negative value, if it fails it will return a negative value and destroy all mutex and unregister all callbacks. av_lockmgr_register is not thread-safe, it must be called from a single thread before any calls which make use of locking are used.
