When there is a match, pcre_exec returns the number of pairs of offsets
in the vector. Since none of your patterns have any substrings, there is
only one pair of offsets (used for the whole match) when there is a match.
When I run the latest pcredemo program using:
C:> pcredemo "abc" "123abc456"
from the Windows console I get:
Match succeeded at offset 3
0: abc
No named substrings
You should use official source from
<
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/>
The latest PCRE version is 8.00 and was released just a few days ago
<
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.00.zip>
There is a CHM help file that contains all the documentation for version
8.00 here:
<
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib/pcre-8.00.chm>
I would suggest to read the page titled NON-UNIX-USE with attention to
how to configure PCRE with CMake. CMake will create a Visual Studio 2005
project you can open and build directly in Visual Studio. If you build a
shared libraries, you will get pcre.dll. If you make a project to build
pcredemo.c all you have to do is configure a dependency on pcre.lib.
Beware of stack overflows. I use the "NoRecurse" option when building
PCRE so that heap rather than stack is used for recursion. If you don't
do so, be sure to allocate adequate stack.
Hope it helps,
