IDebugSymbols3::GetFieldTypeAndOffset method (dbgeng.h)
The GetFieldTypeAndOffset method returns the type of a field and its offset within a container.
Syntax
HRESULT GetFieldTypeAndOffset(
[in] ULONG64 Module,
[in] ULONG ContainerTypeId,
[in] PCSTR Field,
[out, optional] PULONG FieldTypeId,
[out, optional] PULONG Offset
);
Parameters
[in] Module
Specifies the module containing the types of both the container and the field.
[in] ContainerTypeId
Specifies the type ID for the container's type. Examples of containers include structures, unions, and classes.
[in] Field
Specifies the name of the field whose type and offset are requested. Subfields may be specified by using a dot-separated path.
[out, optional] FieldTypeId
Receives the type ID of the field.
[out, optional] Offset
Receives the offset of the field Field from the base memory location of an instance of the container.
Return value
This method may also return error values. See Return Values for more details.
| Return code | Description |
|---|---|
|
The method was successful. |
|
The field Field could not be found in the type specified by ContainerTypeId. |
Remarks
An example of a dot-separated path for the Field parameter is as follows. Suppose the MyStruct structure contains a field MyField of type MySubStruct, and the MySubStruct structure contains the field MySubField. Then the type of this field and its location relative to the location of MyStruct structure can be found by passing "MyField.MySubField" as the Field parameter to this method.
