ipc_pair_mem - creates a pair of mutually connected IPC sockets
#include <libdill.h> int ipc_pair_mem( void* mem, int s);
This function creates a pair of mutually connected IPC sockets.
This function allows to avoid one dynamic memory allocation by storing the object in user-supplied memory. Unless you are hyper-optimizing use ipc_pair instead.
mem: The memory to store the newly created object. It must be at least IPC_PAIR_SIZE bytes long and must not be deallocated before the object is closed.
s: Out parameter. Two handles to the opposite ends of the connection.
The sockets can be cleanly shut down using ipc_close function.
In case of success the function returns 0. In case of error it returns -1 and sets errno to one of the values below.
int s; int rc = ipc_pair(s);
