socketfromfd 0.2.0

socketfromfd is an enhanced version of socket.fromfd() from Python’s standard library. It uses ctypes and libc’s getsockopt() function to auto-detect the file descriptor’s socket family, type and protocol.

>>> import socket
>>> sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> sock
<socket.socket fd=4, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('0.0.0.0', 0)>

>>> from socketfromfd import fromfd
>>> newsock = fromfd(sock.fileno())
>>> newsock
<socket.socket fd=5, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6, laddr=('0.0.0.0', 0)>
