[lwip-users] LWIP port with posix.

[Marcos Díaz]

Hi, first of all I wanted to know if there is some repo with official ports for certain OS for LWIP (sys_arch.c, cc.h, etc)

Then, a second question, I saw this sys_arch.c for a unix port,

https://github.com/pabigot/lwip-contrib/blob/master/ports/unix/sys_arch.c

And we started to use it for another OS with posix support.

My question is, does anybody know why have they implemented sys_sem with posix cond and  mutexes, and not with posix semaphores?

My doubt arose because I wanted to use sys_sem's in a driver as a way to signal a receiving thread for an ethernet interface, from an interrupt, in order to make the driver more portable. But since it is implemented with a mutex, I cant unlock a mutex from the interrupt. Thanks in advance
