UpdateDebugInfoFileEx

The UpdateDebugInfoFileEx function takes the information stored in NtHeaders and updates the corresponding fields in the .DBG file.

BOOL UpdateDebugInfoFileEx(

IN LPSTR ImageFileName,
IN LPSTR SymbolPath,
OUT LPSTR DebugFilePath,
IN OUT PIMAGE_NT_HEADERS NtHeaders,
IN DWORD OldChecksum
);

Parameters
ImageFIleName

The name of the image that is now out of date with respect to its symbol file.

SymbolPath

The path in which to look for the symbol file.

DebugFilePath

The symbol file that was updated.

NtHeaders

The new NT headers.

OldChecksum

The original checksum value. If this value does not match the checksum that is present in the mapped image, the flags in the .DBG file contain IMAGE_SEPARATE_DEBUG_MISMATCH and the last error value is set to ERROR_INVALID_DATA.

Return Values
If the function succeeds, the return value is TRUE.

Remarks
The UpdateDebugInfoFileEx function takes the information stored in NtHeaders and updates the corresponding fields in the .DBG file. Any time an image file is modified, this function should be called to keep the numbers in sync. Specifically, whenever an image checksum changes, the .DBG file should be updated to match.
