EXT_TDOP_GET_FIELD_OFFSET

The EXT_TDOP_GET_FIELD_OFFSET sub-operation of the DEBUG_REQUEST_EXT_TYPED_DATA_ANSI Request operation returns the offset of a member within a structure.

Parameters

Operation

Set to EXT_TDOP_GET_FIELD_OFFSET for this sub-operation.

InData

Specifies the typed data that represents an instance of a structure that contains the member whose offset is being requested.

InStrIndex

Specifies the name of the member whose offset is being requested. The name is a dot-separated path and can contain sub-members. For example, mymember.mysubmember. Pointers on this dot-separated path will automatically be dereferenced. However, a dot operator (.) should still be used here instead of the usual C pointer dereference operator (->).

Out32

Receives the offset of the member within an instance of the structure. This is the number of bytes between the beginning of an instance of the structure and the member.

Status

Receives the status code returned by this sub-operation. This is the same as the value returned by Request.
