| .SH SYNOPSIS |
| .nf |

| .sp |
| .BI "int getrpcport(const char *" host ", unsigned long " prognum \ |
| ", unsigned long " versnum ", unsigned " proto ); |

| .SH DESCRIPTION |
| .BR getrpcport () |
| returns the port number for version |
| .I versnum |
| of the RPC program |
| .I prognum |
| running on |
| .I host |
| and using protocol |
| .IR proto . |
| It returns 0 if it cannot contact the portmapper, or if |
| .I prognum |
| is not registered. |
| If |
| .I prognum |
| is registered but not with version |
| .IR versnum , |
| it will still return a port number (for some version of the program) |
| indicating that the program is indeed registered. |
| The version mismatch will be detected upon the first call to the service. |
