I don’t usually use networking in C or C++, so I can’t say for sure. But I did I find this quote that might explain it:

The reasons for having both 16 and 32 bit functions is that IP and TCP headers use a mix of 16-bit fields like port numbers along with 32-bit IPv4 addresses.

If I understood correctly, the difference is that the returned value is either uint16_t or uint32_t. Otherwise they look the same based on the headers and documentation.

I get the same errors about descriptor, but no mention of mlt or missing libraries.
I tried the flatpak version and that seems to be working.
