structread

[Lawrence D'Oliveiro]

This routine is so useful, I wonder there's nothing like it in module
struct, or anywhere else I'm aware of:

def structread(fromfile, decode_struct) :
"""reads sufficient bytes from fromfile to be unpacked according to
decode_struct, and returns the unpacked results."""
return struct.unpack(decode_struct, fromfile.read(struct.calcsize(decode_struct)))
#end structread

For a non-trivial example of its use, see

Guido is generally opposed to simple one-liners.
