[Jython-users] Problem with jythonc

[dumonts <du...@fi...>]

I use the following function to convert a 'long' python equivalent
into an 'unsigned long long' C eqivalent.
Without using jython, this function works. 
I don't know how i can do it, in another way, to apply jythonc
interpreter on this function.

import struct

def pack (n) :
	# 0 <= n <= 2 ** 64 - 1
	# Convert a 'long' in an 'unsigned long long' C equivalent
	# Representation on 8 octets
	
	p_low = n & (2L ** 31 - 1)
	p_high = (n & (2L ** 64 - 2L ** 32)) >> 32
	return struct.pack ('LL', p_low, p_high)
	
def unpack (s) :
	# Convert an 'unsigned long long' in a 'long' python equivalent
	
	p_low, p_high = struct.unpack ('LL', s)
	return (p_high << 32) + p_low

Thanks a lot,
