I've never heard of \w, and I don't think that's part of the standard regex syntax. Are you sure it's supported by the regcomp() API?

Why don't you just do something like:

^PRT[0-9A-Z]+

Not only is that a more standard syntax, but it seems easier to understand what it means, IMHO.

Hello,

I am using a regex of ^PRT\w+ to select device names to be the letters
PRT followed by at least one digit or letter and am finding that the
execution of regexec only classes names valid if they are PRT followed
by a W. In Regex syntax the \w is supposed to match to a digit or
"word character" and the plus sign means "one or more".

Am wondering if anyone knows what is wrong? I compiled the regex with
REG_EXTENDED + REG_ICASE + REG_NOSUB if that helps.

Regards,
-Paul
