Name

ZMQ_IPC–ZMQ local inter-process communication Transfer Protocol

Synopsis

Inter-process transport uses a system-related IPC mechanism for message communication between local processes.

The inter-process transfer method is now fully implemented on the socket system that provides the UNIX definition.

Addressing

An endpoint includes transport:// followed by an address (for IPC, ipc://address). The transport specifies the underlying system protocol to use. address specifies the specified addresses that need to be connected.

For inter-process transmission, transport refers to the IPC, the address section is defined below.

Bind a socket

When using the Zmq_bind () function to bind a local socket with an IPC transfer, the endpoint should be a file name of any string that uniquely flags the file that will be created. The file name should be the only one in the operating system namespace that operates using IPC. This file name must also meet the operating system's limitations on the format and length of the normal file name.

When the address is *, the zmq_bind () function generates a temporary file name. The caller needs to get this file name using the Zmq_last_endpoint property. See the Zmq_getsockopt (3) function for more details.

All actions that are bound to a file name that already exists will be overloaded. In this case, the IPC protocol is not the same as the TCP or InProc protocol.

Connect a socket

When using the Zmq_connect () function to initiate an IPC connection to a peer, the endpoint needs to be an arbitrary string that uniquely flags a file name. This file name must have been created by the operating system and assigned to a socket that has been manipulated through Zmq_bind ().

Examples

　　Assign an address to a socket

//   Assign The pathname "/tmp/feeds/0" "ipc:///tmp/feeds/0"   0);

　　Connect a socket

// Connect to the   pathname "/tmp/feeds/0""ipc:///tmp/feeds/0"0 );
