I have a string from a text file that look something like this:

long_str = "returns between paragraphs 20102/34.23" - 9203 1232 "test" "basic HTML"

Note: Quotes are part of the string.

int match(char *long_str){
    char * str;
    if ((str = strchr(long_str, '"')) != NULL) str++; // last " ?
    else return 1;
    return 0;
}

Using strstr I'm trying to get the whole substring between the last two quotes: "basic HTML". I'm just not quite sure what would be a good and efficient way of getting that match. I'm open to any other ideas on how to approach this. Thanks
