parameters like:

linkedlist_get(struct linkedlist *l, unsigned int idx)
{
if (l == NULL) {
errno = EINVAL;
return NULL;

Hi,
I have an SQL Query that loads a SQLDataReader object.
The returned record has bit datatype columns that I use to provide
true/false values.
I can't get a definite answer googling on how to test if this field is null.
I get casting errors, and can't check for null on a null data value errors

Okay, I have been handed a python project and working through it I have
had to add a report. I am returning 10 variables the results of an SQL
Query
and as usual the number of results vary from 1 result to 10 results so
I
implemented a check to see if the array item was empty or not. The code
is below based upon the code already in the python project i was
handed.

First i'll introduce myself since I only joined this forum this morning so hey! <waves>
Right to the problem.
I'm reading values from a html file using the getParameter method to produce an applet. Theres 10 sets of data split into 4 sub fields. The applet works fine but i'd like to make the program more robust by checking for null values. Any ideas?
Thanks

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
