ipc_connect_mem - create a connection to remote IPC endpoint
int ipc_connect_mem(const char *addr, void *mem, int64_t deadline);
IPC protocol is a bytestream protocol (i.e. data can be sent via bsend() and received via brecv()) for transporting data among processes on the same machine. It is an equivalent to POSIX AF_LOCAL sockets.
Creates a connection to a peer listening on the file specified by addr argument, in user-supplied memory. The memory is passed in mem argument. It must be at least IPC_SIZE bytes long and can be deallocated only after the socket is closed. Unless you are hyper-optimizing use ipc_connect() instead.
deadline is a point in time when the operation should time out. Use the now() function to get your current point in time. 0 means immediate timeout, i.e., perform the operation if possible or return without blocking if not. -1 means no deadline, i.e., the call will block forever if the operation cannot be performed.
The socket can be cleanly shut down using ipc_close() function.
Newly created socket handle. On error, it returns -1 and sets errno to one of the values below.
char mem[IPC_SIZE]; int s = ipc_connect_mem("/tmp/test.ipc", mem, -1);
