libdill: Structured Concurrency for C

NAME

ipc_connect - creates a connection to remote IPC endpoint

SYNOPSIS

#include <libdill.h>

int ipc_connect(
    const char* addr,
    int64_t deadline);

DESCRIPTION

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 creates a connection to a remote IPC endpoint.

addr: Filename to connect to.

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.

The socket can be cleanly shut down using ipc_close function.

This function is not available if libdill is compiled with --disable-sockets option.

RETURN VALUE

In case of success the function returns newly created socket handle. In case of error it returns -1 and sets errno to one of the values below.

ERRORS

EXAMPLE

int s = ipc_connect("/tmp/test.ipc", -1);
bsend(s, "ABC", 3, -1);
char buf[3];
brecv(s, buf, sizeof(buf), -1);
ipc_close(s);
