File extension XPT - XPCOM Type Library file

xpt file icon: xpt file icon

File extension XPT description:

The XPT file extension is used by Mozilla Firefox for XPCOM Type Libraries. XPCOM type libraries, or "typelibs", are binary interface description files generated by the XPIDL compiler. Type libraries enumerate the methods of one or more interfaces, including detailed type information for each method parameter. Typelibs might be more aptly named "interface libraries", but Microsoft has already established a precedent with their naming scheme and so it suck with it to avoid developer confusion.

Ideally, XPCOM typelibs would be binary-compatible with those generated by Microsoft's MIDL compiler, but the MS typelib format is proprietary. Thus, this document specifies a format quite different from the Microsoft format.

Note that the typelib is not merely a tokenized form of the IDL. Rather, it's intended to accurately represent binary XPCOM interfaces, with annotations derived from the IDL.
