We have discussed this in other threads but in essence the shared data problem can occur whenever two pieces of code share common data and one piece of code can interrupt the other while it is in the middle of using the data. The result is at least corrupt data and often worse. OK, now I see what you mean. But this is not specifically a problem with 'C', is it? An inexperienced assembler programmer could equally suffer from this - especially if they're using someone else's "multibyte" library routines which they don't really understand... |
