| | 14 | .Ft int |
| | 15 | .Fn getrpcport "char *host" "int prognum" "int versnum" "int proto" |
| | 16 | .Sh DESCRIPTION |
| | 17 | The |
| | 18 | .Fn getrpcport |
| | 19 | function |
| | 20 | returns the port number for version |
| | 21 | .Fa versnum |
| | 22 | of the RPC program |
| | 23 | .Fa prognum |
| | 24 | running on |
| | 25 | .Fa host |
| | 26 | and using protocol |
| | 27 | .Fa proto . |
| | 28 | It returns 0 if it cannot contact the portmapper, or if |
| | 29 | .Fa prognum |
| | 30 | is not registered. |
| | 31 | If |
| | 32 | .Fa prognum |
| | 33 | is registered but not with version |
| | 34 | .Fa versnum , |
| | 35 | it will still return a port number (for some version of the program) |
| | 36 | indicating that the program is indeed registered. |
| | 37 | The version mismatch will be detected upon the first call to the service. |
