RpcRegistry(3I) 					    InterViews Reference Manual 					   RpcRegistry(3I)

NAME

       RpcRegistry - name space for finding RPC services

SYNOPSIS

       #include <Dispatch/rpcregistry.h>

DESCRIPTION

       RpcRegistry provides a name space for finding RPC services based on the use of NFS filesystems among a group of hosts.  When an RPC service
       wishes to record its host name and port number, it will give the path of a file in which to store the information.  When a client wants	to
       find  the  RPC  service's  host name and port number, it will give the path of a file from which to read the information.  Usually the path
       will be the name of a file in the current working directory since different hosts may have different absolute pathnames for the	same  file
       in a NFS filesystem.  The RPC service's name space is the name space of the host's filesystem and the file's contents provides the informa-
       tion needed to open a connection to the RPC service.

PUBLIC OPERATIONS

       Each function is a static member function, which means a program can call it without having to instantiate  an  RpcRegistry  object.   Each
       function returns true if it succeeded or false if some error occurred.

       boolean record(const char* path, int port)
	      Record  the  RPC	service's  host name and port number in the given file.  If the file already exists, its previous contents will be
	      lost.

       boolean erase(const char* path)
	      Remove the file which stores the RPC service's host name and port number so that no more clients will be able  to  contact  the  RPC
	      service.

       boolean find(const char* path, char*& hostname, int& port)
	      Open  the  file  which stores the RPC service's host name and port number.  If the file does not exist, return failure silently.	If
	      the file does exist, read the RPC service's host name and port address from it.  If ``hostname'' is nil upon entry, it will  contain
	      the address of a dynamically allocated string upon exit (which must be freed by the caller).
