Java, JVM, JNI and Signal Handling Explained In Simple Terms

Before you use JNI on Unix or Linux - read this!

I always assumed that the SEG in SEGV referred to memory segmentation like that found in x86 real mode, not 'A process will request one or more segments (typically hundred,s thousands etc.)'.

I am glad you have now learned something then :)

SEGV has nothing what so ever todo with Intel 8088 address management. The name 'segment' just got used twice.

Hiya, I went and looked this up for you:

" Intel segmented memory

This usage should not be confused with that of the x86 memory segmentation used by early Intel processors such as the Intel 8086 and Intel 8088, as they did not provide any protection. Any program could access any segment with no restrictions, and a segment consisted of only a starting location and a fixed length of 64 KiB. Segmentation in the Intel 80286 and later provided protection. "

I think Dr Turner's description of segments is a bit rough and ready; I guess he was just trying to make the post simple.
