wpaul 2001/03/27 13:27:33 PST Modified files: lib/libc/rpc clnt_dg.c include/rpc clnt.h Log: Add a CLSET_ASYNC command, which allows us to (ab)use the clnt_dg transport to make asynchronous RPCs. This is needed to help fix ypbind, which can no longer override the clnt_dg_call() method (formerly the clntudp_call() method) due to all the internal descriptor locking code in TI-RPC. Turning on this flag allows us to send an RPC request, then return immediately, and handle a reply later, rather than being forced to do the request and reply in a single function call. Also fix a byte ordering bug: when clnt_dg_call() increments the XID prior to transmitting a request, it uses the raw value, which is wrong. The XID is stored in network byte order, i.e. big-endian. The CLSET_XID and CLGET_XID commands in clnt_dg_control() use ntohl()/htonl() to get the byte ordering right, but because clnt_dg_call() does not do this, using CLSET_XID/CLGET_XID doesn't actually work, unless you're on a big endian host, which we aren't (yet). Fix clnt_dg_call() to byte swap properly when doing the increment.
