.SH NAME
qbipcc.h \- Client IPC API. 

.SH SYNOPSIS
.nf
.B #include <qb/qbipcc.h>
.SH DESCRIPTION
.PP
Lifecycle of an IPC connection.
.PP
An IPC connection is made to the server with \fIqb_ipcc_connect()\fR. This function connects to the server and requests channels be created for communication. To disconnect, the client either exits or executes the function \fIqb_ipcc_disconnect()\fR.
.PP
Synchronous communication
.PP
The function \fIqb_ipcc_sendv_recv()\fR sends an iovector request and receives a response.
.PP
Asynchronous requests from the client
.PP
The function \fIqb_ipcc_sendv()\fR sends an iovector request. The function \fIqb_ipcc_send()\fR sends an message buffer request.
.PP
Asynchronous events from the server
.PP
The \fIqb_ipcc_event_recv()\fR 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 \fIqb_ipcc_event_recv()\fR the \fIqb_ipcc_fd_get()\fR call is used to obtain a file descriptor used in the poll() or select() system calls.
