If you really do just want the number of occurrences of one character,
then I would advise you just to scan the string and count. Using PCRE is
way over the top.

If you want to repeatedly match in a string using the basic PCRE
functions, you need to write a loop and call pcre_exec repeatedly. There
is such a loop in the pcredemo.c sample program.
