Syntax
struct FRWAccessDetector
Remarks
Read write multithread access detector, will check on concurrent write/write and read/write access, but will not on concurrent read access. Note this detector is not re-entrant, see FRWRecursiveAccessDetector and FRWFullyRecursiveAccessDetector. But FRWAccessDetector should be the default one to start with.
