Description
Name
qb_ipcc_connect - Create a connection to an IPC service.
Note
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.
Params
namenameoftheservice.max_msg_sizebiggestmsgsize.
Return Value
NULL (error: see errno) or a connection object.
