Thomas,

Classes such as \s are not a standard part of regular expressions.  Can you point me to documentation that states that regcomp() supports them?  I am very skeptical that regcomp() supports nonstandard regular expression classes like these.

I believe these were part of the Perl extensions to regular expressions.  Java implemented them as well.   But they are not available elsewhere except where the perl extensions are available.

Hi,

Hopefully somebody is smarter than me. The iSphere source member search
(using regular expressions) does not work when using character classes,
such as "\s".

Whatever I try, I cannot make it work.

I tried to convert the pattern and the value to ccsid 37 without success.

I tried retrieving the current ccsid with nl_langinfo(CODESET) and
convert the pattern and value to that ccsid without success.

Last but not least setting the locale with setLocale(LC_ALL:
LC_C_GERMANY) did not help.

Actually I wanted to change the source file search to use SQL function
REGEXP_COUNT. But that one is sooooo sloooow, that nobody wants to use
it. But at least it works.

REGEXP_COUNT takes 1644298 milliseconds when regexec() does the same job
in 8118 milliseconds. That is 200 times faster than SQL!!!

It was incredible if somebody could help me wit that. A working example
running on jobs with ccsid 37 and 273 would be great.

Regards,

Thomas.
