/lib/C/util/

This directory contains source files for use by Lingua Franca programs using the C target. To use a file in this directory, specify a target property as follows:

target C {
    files: ["/lib/c/reactor-c/util/filename", ...],
    ...
};

This causes the lfc or LF IDE to copy the file into your project's src-gen directory. Hence, you can include the file in your C code as follows:

preamble {= 
    #include "filename"
=}
