Требования для функции 'clnt_sperrno'
| Standard | ID | Description |
| SVID.4 | clnt_sperrno.01 | Take the same arguments as clnt_perrno(), but instead of sending a message to the standard error indicating why an RPC call failed, return a pointer to a string which contains the message. |
| SVID.4 | clnt_sperrno.02 | unlike clnt_sperror() and clnt_spcreaterror() [see rpc_clnt_create(RS_LIB)], clnt_sperrno() does not return pointer to static data so the result will not get overwritten on each call. |
