Modem Manager API using

I found the two links below very helpful.  I’ve implemented C code that communicates with
ModemManager via DBus using the DBus API, not the libmm-glib.

Subject: Modem Manager API using


I am trying to get use of ModemManager API in order to develop a C application
that communicates and ask the modem for diverse operations. I've seen some
python and javascript client examples in the ModemManager repository, but
nothing about C programming.

Does anyone know if C coding examples on how to deal with ModemManager are available on the net, just to be used as a reference, as I have never
programmed using D-Bus??

Both ModemManager and libmm-glib are called high-level APIs, but I'm not sure
what are the difference between each other apart from the fact, as long as I
understand, that libmm is invoked using its own library functions wether
ModemManager is invoked using its D-bus methods (maybe I'm confused about how it works). I don't know if I should develop my program to use libmm or if it
should call ModemManager methods (or even if ModemManager internally uses libmm

Best regards.
