Hello,

for me this looks like

if (0 < 10 && lprgn != NULL)

what is the same like

if (lprgn != NULL)

I thing you meant something different

Note that warned is defined to be static.
Maybe go back in your corner and find out what that means? :-)
(or it might just be that you missed the static part)

The variable 'warned' doesn't actually turn out to be zero all of the
time.  It is a static variable, so it is initialized once to zero when
the program starts, but the difference between  this and a regular
non-static variable is that this static variable holds whatever value
it contains.  If this code snippet runs then warned will increase by
one each time and this new value will not be set back to zero the next
time the block runs.

That wasnt very clear so I'll try to explain better.  The bottom line
is that the value of the static variable is retained between repeated
function calls to the same function.

See http://www-ee.eng.hawaii.edu/Courses/EE150/Book/chap14/subsection2.1.1.6.htm...
for more information.
