Hi, I'm trying to use a C library to handle mqtt messages from GForth. I use Mosquitto as a message broker (on a Raspberry Pi 3).
The header file for mosquito can be found here: https://mosquitto.org/api/files/mosquitto-h.html I get the information about GForth’s C Interface from https://gforth.org/manual/C-Interface.html At the moment, I'm struggling on the function ‘mosquitto_new’. More precisely, my issue is that this function returns a pointer to a struct (« Pointer to a struct mosquitto on success »), which I can't figure out how to code. Here's my code: ********* c-library libmosquitto \c #include <sys/types.h> \c #include <mosquitto.h> c-function mosquitto_lib_init mosquittoLibInit -- void c-function mosquitto_connect mosquittoConnect a a n n -- void c-function mosquitto_subscribe mosquittoSubscribe a n a a -- void c-function mosquitto_loop mosquittoLoop a n n -- void c-function mosquitto_new mosquittoNew a n void -- "What do I put here?" end-c-library ******* I get an « Invalid name argument » error for every type I try. Note that I'm not a C programmer, so I might be struggling with something obvious. Any help will be appreciated Thank you Mario Envoyé de mon iPad
