IDebugSymbols3::GetModuleByOffset method (dbgeng.h)

Article
02/22/2024

The GetModuleByOffset method searches through the target's modules for one whose memory allocation includes the specified location.

Syntax

HRESULT GetModuleByOffset(
  [in]            ULONG64  Offset,
  [in]            ULONG    StartIndex,
  [out, optional] PULONG   Index,
  [out, optional] PULONG64 Base
);

Parameters

[in] Offset

Specifies a location in the target's virtual address space which is inside the desired module's memory allocation -- for example, the address of a symbol belonging to the module.

[in] StartIndex

Specifies the index to start searching from.

[out, optional] Index

Receives the index of the module. If Index is NULL, this information is not returned.

[out, optional] Base

Receives the location in the target's memory address space of the base of the module. If Base is NULL, this information is not returned.

Return value

This method may also return error values. See Return Values for more details.

Return code	Description
S_OK	The method was successful.

Remarks

Starting at the specified index, this method returns the first module it finds whose memory allocation address range includes the specified location. If the target has more than one module whose memory address range includes this location, then subsequent modules can be found by repeated calls to this method with higher values of StartIndex.

For more information about modules, see Modules.
