rpcstream(3I) InterViews Reference Manual rpcstream(3I)NAME
rpcstream - iostreamb specialized to RPC requests
SYNOPSIS
#include <Dispatch/rpcstream.h>
DESCRIPTION
rpcstream, irpcstream, and orpcstream specialize iostream, istream, and ostream, respectively, to RPC requests. That is, the associated
streambuf will be an rpcbuf. Conversions will be formatted (that is, ASCII) so datums will need to be separated by space characters.
CONSTRUCTORS
rpcstream()
Construct an unopened rpcstream.
PUBLIC OPERATIONS
void listen(int port)
void connect(const char* host, int port)
Create a connection. Any failure sets ios::failbit in the error state.
int accept()
Accept a pending connection and return the new file descriptor.
void attach(int fd)
Attach to a pre-existing connection.
void close()
Break a connection. The error state is cleared except on failure.
void nonblocking(boolean)
void verbose(boolean)
Enable or disable non-blocking I/O and/or printing of error messages.
rpcbuf* rdbuf()
Return a pointer to the rpcbuf created by the rpcstream.
boolean incomplete_request()
void incomplete_request(boolean)
Get or set a flag. Used by the operations that insert an RpcHdr into an rpcstream or extract an RpcHdr from an rpcstream.

RpcHdr(3I) InterViews Reference Manual RpcHdr(3I)NAME
RpcHdr - header for remote procedure calls
SYNOPSIS
#include <Dispatch/rpchdr.h>
DESCRIPTION
An RpcHdr enables an RPC request to be sent or received. To send an RPC request, you would insert an RpcHdr into an rpcstream followed by
any arguments and then flush the rpcstream if you wanted the request to be sent immediately. The rpcstream automatically fills in each RPC
request's length field. To receive an RPC request, you would extract an RpcHdr from an rpcstream and examine the ``request()'' member to
determine which additional arguments need to be extracted as well. You can examine the ``ndata()'' member too if you need to estimate how
much space to allocate.
CONSTRUCTORS
RpcHdr(void* writer, int request)
RpcHdr(int request)
RpcHdr()
Construct an initialized header for an outgoing RPC request (first two constructors) or construct an uninitialized header for an
incoming RPC request (third constructor). To initialize the header, you'll have to store the request's protocol number. You can
also store the address of the writer sending the RPC request if you want to route the RPC request to a specific reader on the peer's
side.
PUBLIC OPERATIONS
unsigned long reader()
int request()
unsigned int ndata()
Get information about the RPC request. ``reader()'' identifies the reader which should handle the RPC request. ``request()'' iden-
tifies the action that should be performed. ``ndata()'' gives the number of data bytes following the header, which may be useful
for estimating the amount of space that must be allocated to store an argument.
