- Mike,
- I wish I could tell you that it would, but since I have not seen the
- problem (and actually have been out of VLSI circles for a couple years) I
- can't say that it will. However, if you did not patch the header file
- that Christos mentioned (net.h) you could certainly be getting all sorts
- of problems. The index into the array is defined as char. If the offset
- has the 7th bit as one, it is treated as a NEGATIVE offset. This will
- screw you to no end. It is imperative that you make it an unsigned short
- or something like that.
