UpdateDebugInfoFileEx

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

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

Parameters

ImageFIleName

Pointer to a null-terminated string that specifies the name of the image that is now out of date with respect to its symbol file.

SymbolPath

Pointer to a null-terminated string that specifies the path in which to look for the symbol file.

DebugFilePath

The symbol file that was updated.

NtHeaders

Pointer to an IMAGE_NT_HEADERS structure that specifies the new NT header information.

OldChecksum

Specifies the original checksum value. If this value does not match the checksum that is present in the mapped image, the flags in the symbol 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.

If the function fails, the return value is FALSE.

Remarks

The UpdateDebugInfoFileEx function takes the information stored in the IMAGE_NT_HEADERS structure and updates the corresponding fields in the symbol 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 symbol file should be updated to match.
