qbipcc.h - Client IPC API.

#include <qb/qbipcc.h>

Lifecycle of an IPC connection.

An IPC connection is made to the server with qb_ipcc_connect(). This function connects to the server and requests channels be created for communication. To disconnect, the client either exits or executes the function qb_ipcc_disconnect().

Synchronous communication

The function qb_ipcc_sendv_recv() sends an iovector request and receives a response.

Asynchronous requests from the client

The function qb_ipcc_sendv() sends an iovector request. The function qb_ipcc_send() sends an message buffer request.

Asynchronous events from the server

The qb_ipcc_event_recv() function receives an out-of-band asynchronous message. The asynchronous messages are queued and can provide very high out-of-band performance. To determine when to call qb_ipcc_event_recv() the qb_ipcc_fd_get() call is used to obtain a file descriptor used in the poll() or select() system calls.
