This indicates that an error occurred in the <B>JudyLIns()</B> function
at line 321.  Line 1234 is the line in 'YourCfile.c' where the
<B>JLI()</B> call failed.  JU_ERRNO_* == 2 is equal to JU_ERRNO_NOMEM
(as defined in the <B>Judy.h</B> file).  The ID number indicates the
source line number in the function where the error originated.  Your
program then terminates with an <I>exit(1);</I>.  By default, both
categories of Judy error returns are printed this way.  (The 'ID == 321'
is for die hards that want more detail or for debugging Judy itself.)

<DT><B>2) Disable Macro Error Handling</B> </DT>
<DD>
When your program is "bug free", the only errors returned should be
<I>malloc()</I> failures.  Therefore all error returns can be treated as
a <I>malloc()</I> failure.  By using the below <B>#define</B>, all
error testing and printing is turned off.  Additional code needs to be
added to the code that can have <I>malloc()</I> failures.  Judy was
designed to leave the same data in the array before the call if a
<I>malloc()</I> fail occurs.  (During testing of Judy, we found very few
<I>malloc()</I>/OS's that were bug free after a <I>malloc()</I> failure.
Sometimes it took weeks to discover because most systems go into a

if (RC_int == JERR) goto out_of_memory_handling;
...

J1U(RC_int, P1Array, Index);
if (RC_int == JERR) goto out_of_memory_handling;
...

</PRE>
Note:  Without 'JUDYERROR_NOTEST' defined, the 'goto
out_of_memory_handling' will never be executed and will be optimized out
by the compiler.  The default method will be used -- Macro will print
error information if an error occurs as explained above.
<P>
With 'JUDYERROR_NOTEST' defined, the 'goto out_of_memory_handling' will
be executed when an error occurs -- which should only happen when
<I>malloc()</I> fails.
<DT><B>3) User-Specified JUDYERROR() Macro Method</B> </DT>
<DD>
The <B>JUDYERROR()</B> macro (in <B>Judy.h</B>) provides flexibility for
handling error returns as needed to suit your program while still using
the Judy array macros instead of function calls.  You can use a
different <B>JUDYERROR()</B> macro to suit your needs.  The following
example is a possible alternative to the default. It is used to
distinguish between the two types of errors (described above), and
explicitly test for the remaining JU_ERRNO_NOMEM errors possible in your
program.
