Longint?!

[Ivo]

Pythoneers,
I am trying to reed a long integer (4 byte value like in pascal) in python
but i don't seem to succeed.

It's from a binary file where from a certain offset in the file 4 bytes
(longint) tell how long a header is.

because I don't have to assign a type to a variable I don't know how to
ensure i get the longint type read from the file.

Help very much appreciatend.

There is an sscanf module around (1995 Stichting Mathematisch Centrum)
which has a 'long' format control.
If you can't find it, I can send you the file.

You must read it as binary and use struct.unpack() to convert
to long integer.

I will try the struct...
Thanx
