Retrieves the omap tables within a loaded module.

Syntax


BOOL WINAPI SymGetOmaps(
  _In_  HANDLE   hProcess,
  _In_  ULONG64  BaseOfDll,
  _Out_ POMAP    *OmapTo,
  _Out_ PDWORD64 cOmapTo,
  _Out_ POMAP    *OmapFrom,
  _Out_ PDWORD64 cOmapFrom
);

Parameters

hProcess [in]

A handle to a process. This handle must have been previously passed to the SymInitialize function.

BaseOfDll [in]

The base address of the module.

OmapTo [out]

An array of address map entries to the new image layout taken from the original layout. For details on the map entries, see the OMAP structure.

cOmapTo [out]

The number of entries in the OmapTo array.

OmapFrom [out]

An array of address map entries from the new image layout to the original layout (as described by the debug symbols). For details on the map entries, see the OMAP structure.

cOmapFrom [out]

The number of entries in the OmapFrom array.

Return value

If the function succeeds, the return value is TRUE.

If the function fails (the omap is not found), the return value is FALSE. To retrieve extended error information, call GetLastError.
