# RpcWriter(3)

write RPC requests to a server

## NAME

RpcWriter - write RPC requests to a server

## SYNOPSIS

**#include \<Dispatch/rpcwriter.h\>**

## DESCRIPTION

An RpcWriter (actually, an instance of a class derived from RpcWriter) writes RPC requests to a server.  Derived classes should add member functions that send RPC requests corresponding to the RPC service's protocol.

## CONSTRUCTORS

- **RpcWriter(const char\* path, boolean fatal, boolean binary)**

  - **RpcWriter(const char\* host, int port, boolean fatal, boolean binary)**

  - **RpcWriter(int fd, boolean fatal, boolean binary)**

  - **RpcWriter(rpcstream\* server)**

  Open a connection to an RPC service at its registered host name and port number, or give the host name and port number needed to open a connection to the RPC service, or give the number of an already open file descriptor, or give the address of an already open rpcstream (connection).  Negotiate the I/O format (binary or formatted) if opening a connection.  Terminate the program if errors should be fatal.
