Требования для функции 'clnt_sperror'
| Standard | ID | Description |
| SVID.4 | clnt_sperror.03 | 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. |
| SVID.4 | clnt_sperror.01 | Like clnt_perror(), except that (like clnt_sperrno()) it returns a string instead of printing to standard error. |
| SVID.4 | clnt_sperror.02 | However, clnt_sperror() does not append a NEWLINE at the end of the message. |
