How to know when it's possible to bind a socket on an unprivileged port?

Hi,
For a purpose of testing I need a function which could tell me whether
it is possible to bind sockets on privileged ports or not.
I wrote down this simple function. It seems reasonably working to me
but I'd like to hear your opinion first.
Thanks in advance.
import socket, errno
def bind_on_privileged_ports(port=21):
"""Return True if it is possible to bind sockets on privileged
ports (< 1024)."""
try:
s = socket.socket()
s.bind(("", port))
except socket.error, err:
if err[0] == errno.EACCES:
return False
s.close()
return True
