GC.query

BlkInfo query(return scope const void * p) nothrow

Returns aggregate information about the memory block containing p. If p references memory not originally allocated by this garbage collector, if p is null, or if the garbage collector does not support this operation, BlkInfo.init will be returned. Typically, support for this operation is dependent on support for addrOf.

Parameters

`p`	A pointer to the root or the interior of a valid memory block or to null.

Returns

Information regarding the memory block referenced by p or BlkInfo.init
