Coming back with a new question. I am not a pro with C, so forgive me if the code is ugly. I would like to pass an array of string to a C function, loop into it and compare each string in that array if it matches a substring. Something I am pretty sure it is very easy to accomplish, but i am having issues. I google for an example, but what I found was related to numbers. Any help, clue would be nice. 
my @a = ("AAAA", "BBBB", "CCCCC");
my $size = $#a;
my $p1 = pack "(A*)*", @a;
print array_search($size,$p1,"B");


__END__
__C__
#include <stdio.h>
void hello_world() {
        printf ("Hello CDRs checkers!\n");
}
//s1 is the substring, s2 is the string
int fastcmp ( char *p1, char *p2 ) {
    int i;
    for( i = 0; i < sizeof(p1); ++i ) {
        if( p1[i] != p2[i] ) {
            return 0;
        }
    }
    return 1;
}
int array_search(int size,char *a1, SV *s1){
        STRLEN bytes1;
        char *p1;
        char *p2 = (char *) a1;
        long a1_size,i;
        p1 = SvPV(s1,bytes1);
        for(i=0;i<size;++i){
            if (fastcmp(p1,p2[i])){
                return 1;
            }
        }
        return 0;
}
