Syntax

DWORD (*pReadRegistryFromOEM)(
  DWORD dwFlags, 
  DWORD lpData, 
  DWORD cbData
);

dwFlags
[in] Read options specified by the OS.

REG_READ_BYTES_START indicates reading must start from the beginning of the registry file.

lpData
[in] Pointer to a buffer allocated by the OS.

You must load the buffer with registry bytes up to a maximum of cbData.

cbData
[in] Size, in bytes, of the buffer that lpData points to.

This value is passed in by the OS.

If 0 is returned, the end of file (EOF) has been reached.

If -1 is returned, your function's read functionality has faulted and the OS should load the default registry.
