IPC_PAIR_MEM(3) libdill Library Functions IPC_PAIR_MEM(3) NAME ipc_pair_mem - creates a pair of mutually connected IPC sockets SYNOPSIS #include <libdill.h> int ipc_pair_mem( struct ipc_pair_storage* mem, int s[2]); DESCRIPTION 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 structure to store the newly created object in. It 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. RETURN VALUE In case of success the function returns 0. In case of error it returns -1 and sets errno to one of the values below. ERRORS * ECANCELED: Current coroutine was canceled. * EMFILE: The maximum number of file descriptors in the process are already open. * ENFILE: The maximum number of file descriptors in the system are already open. * ENOMEM: Not enough memory.
