Re: [libvirt] [PATCH] Add interface object list manipulation functions.

These functions are useful for an implementation of an interface driver that doesn't use a library that manages its own list of interfaces (as netcf does), for example the test interface driver.

+ +int virInterfaceFindByMACString(const virInterfaceObjListPtr interfaces, + const char *mac, + virInterfaceObjPtr *matches, int maxmatches) +{ + unsigned int i, matchct = 0; + + for (i = 0 ; i < interfaces->count ; i++) { + int lock_for_caller = 0; + virInterfaceObjLock(interfaces->objs[i]); + if (STREQ(interfaces->objs[i]->def->mac, mac)) { + if (matchct < maxmatches) { + matches[matchct] = interfaces->objs[i]; + lock_for_caller = 1; + } + matchct++; + } + if (!lock_for_caller) { + /* it is the caller's responsibility to unlock *all* matches */ + virInterfaceObjUnlock(interfaces->objs[i]); + } + }
