Hi, I am very new when it comes to this topic so please be forgiving. I
am an intern and I could use some help. I have followed another post
from this site since I have a similar problem but it didn't help.
Here's my problem: I have a function (FetchData(), shown below) and this
function works perfectly in a 32-bit HP-UX i64 environment. I am trying
to compile and use this function in 64-bit and it CORE dumps on the line
notified below. I ran my application in GDB and attempted to trace
through but I can't seem to make sense of it and I was hoping for some
expertise. Here is the GDB outputs and at the bottom is the source
code. Any help would be greatly appreciated. Thanks in advance.
