ipc_conn_io_create()

ipc_conn_io_t * ipc_conn_io_create	(	ipc_t *	ipc,
		bool	is_server_side )

Create a new IPC connection io descriptor.

Parameters

ipc	The IPC object to create the connection for
is_server_side	Whether this is the server side of the connection

Returns

ipc_conn_io_t* A new IPC connection io descriptor

Here is the call graph for this function:

ipc_create()

io_t * ipc_create	(	const char *	name,
		size_t	max_pending_connections )

Create a new IPC server.

Parameters

name	The name of the server
max_pending_connections	The maximum number of pending connections to allow

Returns

A new io_t object that represents the server, or an error code on failure

Note

The io_t returned by this function is only to accept new connections or close the server, reading or writing to it will fail.

ipc_accept()

io_t * ipc_accept

(

io_t *

server

)

Accept a new connection on an IPC server.

Parameters

server

The server to accept a connection on

Returns

An io_t for the server side of the connection, or an error code on failure

Definition at line 121 of file ipc_io.c.

Here is the call graph for this function:

ipc_connect()

io_t * ipc_connect	(	const char *	name,
		size_t	buffer_size )

Connect to an IPC servers.

Parameters

name	The name of the server to connect to
buffer_size	The size of a shared-memory buffer to use for the connection

Returns

A new io_t object that represents the connection, or an error code on failure
