hi,I port a usb driver form freebsd for 4G dongle, it work ,but I cannot use gethostbyname ,I add some code for debug,find in freebsd/lib/libc/net/gethostnamadr.c line 581 _nsdispatch return failure, in function _nsdispatch ,
if (isthreaded) {
result = _pthread_rwlock_rdlock(&nss_lock);
if (result != 0) {
printf("nsdispatch pthread rd lock failure %d!\n",result);
result = NS_UNAVAIL;
goto fin;
}
}
_pthread_rwlock_rdlock return invalid, can you give me some advise? how can i let gethostbyname work?
