trylock

Tries to lock this.

If this is already locked by another thread, it immediately returns false . Otherwise it locks this and returns true.

Mutex is neither guaranteed to be recursive nor to be non-recursive. As such, calling @lock on a Mutex that has already been locked by the same thread results in undefined behaviour (including but not limited to deadlocks or arbitrary return values).

Parameters:

this

a Mutex

Returns:

true if this could be locked
