LOAD_DLL_DEBUG_INFO info  Overview  Group

The LOAD_DLL_DEBUG_INFO structure contains information about a dynamic-link library (DLL) that has just been loaded.

typedef struct _LOAD_DLL_DEBUG_INFO { // lddi 

    HANDLE hFile; 

    LPVOID lpBaseOfDll; 

    DWORD  dwDebugInfoFileOffset; 

    DWORD  nDebugInfoSize; 

    LPVOID lpImageName; 

    WORD fUnicode; 

} LOAD_DLL_DEBUG_INFO; 

 

Members

hFile

Identifies a handle of the DLL. If this member is NULL, the handle is not valid. Otherwise, the member is opened for reading and read-sharing in the context of the debugger.

lpBaseOfDll

Points to the base address of the DLL in the address space of the process loading the DLL.

dwDebugInfoFileOffset

Specifies the offset to the debugging information in the file identified by the hFile member. The kernel expects the debugging information to be in CodeView 4.0 format. This format is currently a derivative of Common Object File Format (COFF).

nDebugInfoSize

Specifies the size, in bytes, of the debugging information in the file. If this value is zero, there is no debugging information.

lpImageName

Points to the filename associated with hFile. This member may be NULL, or it may contain the address of a string pointer in the address space of the process being debugged. That address may, in turn, either be NULL or point to the actual filename. If fUnicode is a nonzero value, the name string is Unicode; otherwise, it is ANSI.

This member is strictly optional. Debuggers must be prepared to handle the case where lpImageName is NULL or *lpImageName (in the address space of the process being debugged) is NULL. Specifically, this release of Windows NT will never provide an image name for a create process event, and it will not likely pass an image name for the first DLL event. This version of Windows NT will also never provide this information in the case of debugging events that originate from a call to the DebugActiveProcess function.

fUnicode

Indicates whether a filename specified by lpImageName is Unicode or ANSI. A nonzero value for this member indicates Unicode; zero indicates ANSI.
