Re: [lwip-users] Reentrency problem within mem.c module

[Siva Velusamy]

The solution of this problem, once found was simply to add SYS_ARCH_PROTECT protection mechanism as an alternative to sys_sem_xxx function already present. The generic form is :

#if SYS_LIGHTWEIGHT_PROT
   SYS_ARCH_PROTECT(level)
#else
   sys_sem_wait(mem_sem)
#endif /* SYS_LIGHTWEIGHT_PROT */


I want to have your advice to known if it's something that must be corrected (I believe so), or left as is.

Yes, you need to have SYS_ARCH_PROTECT properly defined if you do not implement the sys_arch layer.
