The requirement for caller: (processedSize != NULL).
The callee can allow (processedSize == NULL) for compatibility reasons.
if (size == 0), this function returns S_OK and (*processedSize) is set to 0.
if (size != 0)
{
Partial read is allowed: (*processedSize <= avail_size && *processedSize <= size),
where (avail_size) is the size of remaining bytes in stream.
If (avail_size != 0), this function must read at least 1 byte: (*processedSize > 0).
You must call Read() in loop, if you need to read exact amount of data.
}
If seek pointer before Read() call was changed to position past the end of stream:
if (seek_pointer >= stream_size), this function returns S_OK and (*processedSize) is set to 0.
ERROR CASES:
If the function returns error code, then (*processedSize) is size of
data written to (data) buffer (it can be data before error or data with errors).
The recommended way for callee to work with reading errors:
1) write part of data before error to (data) buffer and return S_OK.
2) return error code for further calls of Read().
