flingfd is a small, standalone C library to pass file descriptors across processes on Linux.

By default, flingfd installs in/usr/local. If you want to change where it gets installed, edit thePREFIX in the Makefile.

  $ make && sudo make install

The library consists of two functions declared inflingfd.h:

boolflingfd_simple_send(constchar*path,intfd);intflingfd_simple_recv(constchar*path);

When you want to send a file descriptor, callflingfd_simple_send and receive it in the other process withflingfd_simple_recv. Make sure you use the samepath argument in both processes -- that determines which process gets the file descriptor.

Here's an example of sendingstdout to another process:

#include<flingfd.h>voidsend_my_stdout() {intfd=fileno(stdout);flingfd_simple_send("/tmp/some_unique_path",fd);  }

And here's the other process writing to the sender'sstdout:

#include<flingfd.h>voidwrite_to_their_stdout() {intfd=flingfd_simple_recv("/tmp/some_unique_path");write(fd,"Hello world\n",12);  }

When you're done writing your code, link against the library with-lflingfd.
