VB6 and yapi.dll
Each entry point from the yapi.dll is duplicated. You will find one regular C-decl version and one
Visual Basic 6 compatible version, prefixed with
vb6_ .
21.4. Porting the high level library
As all the sources of the Yoctopuce API are fully provided, you can very well port the whole API in
the language of your choice. Note, however, that a large portion of the API source code is
automatically generated.
Therefore, it is not necessary for you to port the complete API. You only need to port the yocto_api
file and one file corresponding to a function, for example yocto_relay . After a little additional work,
Yoctopuce is then able to generate all other files. Therefore, we highly recommend that you contact
Yoctopuce support before undertaking to port the Yoctopuce library in another language.
Collaborative work is advantageous to both parties.
