Linking Technologies: C Language Actions
To call into a C-function inside a library (eg. shared library / dll)
or to implement a computation algorithm in C,
you can define a C-action. You would also use this to call into a C++ framework via C entries annotated as "extern C".
As a first simple example, create one with a single input pin (named "inPin" with type "String") and type in the code:
execute
printf("hello %s\n", stringValue(inPin));
This can now be connected to any other expecco actions and a string passed to it via the input pin. Here, an expecco dialog pops up, and the entered string is sent to the C function:
