widl - Wine Interface Definition Language (IDL) compiler  


widl [options] infile.idl
widl [options] --dlldata-only name1 [name2 ...]  


When no options are used the program will generate a header file, and possibly client and server stubs, proxy and dlldata files, a typelib, and a UUID file, depending on the contents of the IDL file. If any of the options -c, -h, -p, -s, -t, -u, or --local-stubs are given, widl will only generate the requested files, and no others. When run with --dlldata-only, widl will only generate a dlldata file, and it will contain a list of the names passed as arguments. Usually the way this file is updated is that each time widl is run, it reads any existing dlldata file, and if necessary regenerates it with the same list of names, but with the present proxy file included.

When run without any arguments, widl will print a help message.
