Public Member Functions

int findaddr (int msec_timeout, WvStringParm name, WvIPAddr const **addr, WvIPAddrList *addrlist=NULL)
 Return -1 on timeout, or the number of addresses found, which may be 0 if the address does not exist.
int findname (int msec_timeout, WvIPAddr *ipaddr, char **name)
void clearhost (WvStringParm hostname)
void pre_select (WvStringParm hostname, WvStream::SelectInfo &si)
 add all of our waiting fds to an fd_set for use with select().
bool post_select (WvStringParm hostname, WvStream::SelectInfo &si)
 determines whether the resolving process is complete.

int WvResolver::findaddr ( int  msec_timeout,
WvStringParm  name,
WvIPAddr const **  addr,
WvIPAddrList *  addrlist = NULL 
)

Return -1 on timeout, or the number of addresses found, which may be 0 if the address does not exist.

addrlist, if present, has to be an initialized list. addr points to an internal WvIPAddr and will be deleted automatically.
