qb_ipcc_connect - Create a connection to an IPC service.

#include <qb/qbipcc.h>

qb_ipcc_connection_t * qb_ipcc_connect(
    const char   *name,
    size_t        max_msg_size

name name of the service.

max_msg_size biggest msg size.

NULL (error: see errno) or a connection object.

It is recommended to do a one time check on the max_msg_size value using qb_ipcc_verify_dgram_max_msg_size BEFORE calling the connect function when IPC_SOCKET is in use. Some distributions while allow large message buffers to be set on the socket, but not actually honor them because of kernel state values. The qb_ipcc_verify_dgram_max_msg_size function both sets the socket buffer size and verifies it by doing a send/recv.
