Function module_debug 

pub unsafe extern "C" fn module_debug(
    enable: c_int,
    file: *const c_char,
) -> c_int

Enable or disable debugging into the given file

The enable parameter is a boolean integer with values 0 (false) or 1 (true) to disable or enable (respectively) verbose file debugging.

The file parameter is the NUL-terminated path where the debug file should be written to.

Your module implementation must export it’s own version of this function, unless your build system builds and links with its own version of module-utils.c from the speech-dispatcher distribution.
