Holy cow, I wrote a book!
One of the many gotchas of working with
is accidentally using functions on them which were designed
to operate on single-null-terminated strings.
Now, you do need to use those single-null-terminated strings,
but you also need to know when they won't do what you want.
One of the responses to my psychic detection that somebody
passed a single-null-terminated string to
"Oh, no, I double-null-terminated it. Look:
sprintf(szDeletePath, "%s\0", file_to_delete);
See, I put an extra \0 at the end."
Well, yeah, you put an extra \0 at the end, but
all that does is terminate the format string.
The sprintf function accepts its format string
as a traditional null-terminated string.
When it sees the \0 you stuck into the string,
it thinks it found the end of the string.
It can't read your mind and say,
"Oh, this null is not a terminator.
It's an embedded null."
A simple mistake, but something that needs to be called out.
To be fair, most people recognize this mistake as soon as it's
pointed out to them.
You just have to remember to point it out to them.
