Syntax

HRESULT LoadRegTypeLib( 
  REFGUID rguid, 
  unsigned short wVerMajor, 
  unsigned short wVerMinor, 
  LCID lcid, 
  ITypeLib FAR* FAR* pptlib 
);

Returns the HRESULT values shown in the following table.

TYPE_E_IOERROR	The function could not read from the file.
TYPE_E_INVALIDSTATE	The type library could not be opened.
TYPE_E_INVDATAREAD	The function could not read from the file.
TYPE_E_UNSUPFORMAT	The type library has an older format.

Only typelib2 type libraries are supported.

The function LoadRegTypeLib defers to LoadTypeLib to load the file.

LoadRegTypeLib compares the requested version numbers against those found in the system registry, and takes one of the following actions:

If a registered library exactly matches the requested major and minor version numbers, that type library is loaded.
If one or more registered type libraries exactly match the requested major version number, and has a greater minor version number than that requested, the one with the greatest minor version number is loaded.
If no registered type library exactly matches the requested major version number (or if none of those that exactly match the major version number have a minor version number greater than or equal to the requested minor version number), LoadRegTypeLib returns an error.

Passing invalid (and under some circumstances NULL) pointers to this function causes an unexpected termination of the application.
