Read a concatenated 64-bit integer.
Read a concatenated 64-bit integer.Parses a concatenated 64-bit signed integer. Consecutive integers are, of course, space-delimited. The function knows about this (it uses sscanf() to the dirty work).
The nomenclature was inspired from the Major BBS, which was 16-bit. There, ints were 16 bits long (eurgh) and longs were a nice 32 bits. We go a bit further and read 64-bit `longs'.
