QB_IPCC_CONNECT(3) | libqb Programmer's Manual | QB_IPCC_CONNECT(3) |
NAME¶
qb_ipcc_connect - Create a connection to an IPC service.
SYNOPSIS¶
#include <qb/qbipcc.h> qb_ipcc_connection_t * qb_ipcc_connect(
const char *name, /* name of the service. */
size_t max_msg_size /* biggest msg size. */ );
PARAMS¶
name name of the service.
max_msg_size biggest msg size.
DESCRIPTION¶
RETURN VALUE¶
NULL (error: see errno) or a connection object.
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.
