Umm...nothing obviously wrong. But I don't think the code does what you said.
The two elements in ResultStruct seem not for string at all. ResultID looks
like some type of integer and CurrentRec is initialized with a single '0' so
what you trying to write is only couples of bytes (8 maxmium possibably).
However the size issue itself doesn't warrant the error you saw. They look
consistant.
What I can recommand is try to get the debugger working. Step through the
lines and check all the values involved. What development tool are you using?
Both CodeWarrior and GCC have easy to use debuggers.
