DigestFunction callback function
An application-defined callback function used by the ImageGetDigestStream function to process data.
The DIGEST_FUNCTION type defines a pointer to this callback function. DigestFunction is a placeholder for the application-defined function name.
- refdata [in]
A user-supplied handle to the digest. This value is passed as a parameter to the ImageGetDigestStream function.
- pData [in]
The data stream.
- dwLength [in]
The size of the data stream, in bytes.
If the function succeeds, the return value should be TRUE. If the function fails, the return value should be FALSE.
All ImageHlp functions, such as this one, are single threaded. Therefore, calls from more than one thread to this function will likely result in unexpected behavior or memory corruption. To avoid this, you must synchronize all concurrent calls from more than one thread to this function.
