ipc_done - half-closes a IPC connection
#include <libdill.h> int ipc_done( int s, int64_t deadline);
IPC protocol is a bytestream protocol for transporting data among processes on the same machine. It is an equivalent to POSIX AF_LOCAL sockets.
This function closes the outbound half of ICP connection. This will cause the peer to get EPIPE error after it has received all the data.
s: The IPC connection handle.
deadline: A point in time when the operation should time out, in milliseconds. 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.
This function is not available if libdill is compiled with --disable-sockets option.
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 ls = ipc_listen("/tmp/test.ipc", 10); int s = ipc_accept(ls, -1); bsend(s, "ABC", 3, -1); char buf; brecv(s, buf, sizeof(buf), -1); ipc_close(s); ipc_close(ls);
