[lwip-users] sys_arch_sem_wait

[Fabian Koch]

Hey all,

a short question about sys_arch_sem_wait().
When someone is waiting for it, and it gets an eror/deleted.
Is that a serious condition that shouldn't
hapen or should it just return the usual SYS_ARCH_TIMEOUT?

At the moment we have an Assertion
in there (in a define called "IF_DEBUG_HALT") and it sometimes
fires in strange situations.

u32_t sys_arch_sem_wait(sys_sem_t sem,
u32_t timeout){
        long
               
       lStart = (long)OsGetTime();
        unsigned
char        bResult;
        
        if(!timeout){
         
      bResult = OsSemEnter((unsigned long)sem);
         
      if(!bResult){//invalid or deleted while waiting
on
         
              IF_DEBUG_HALT;
         
      }
        }
else {
         
      bResult = OsSemWait((unsigned long)sem, timeout);
        }
        if(bResult){
         
      return((u32_t)(((long)OsGetTime()) - lStart));
        }
else {
         
      return(SYS_ARCH_TIMEOUT);
        }
}

regards,
Fabian
