Re: Update to mail() function help

Hi Rasmus, I'm having a (likely) small problem here. I just preface this problem with the fact that I do not have a lot of C experience (which is the cause of my problem) -- most of my experiences are in Java, PHP and the like. I have added the following into php_mail() in mail.c: zval *server_name; <snip, snip...> fprintf(sendmail, "To: %s\n", to); fprintf(sendmail, "Subject: %s\n", subject); zend_hash_find(PG(http_globals)[TRACK_VARS_SERVER]->value.ht, "SERVER_NAME", sizeof("SERVER_NAME"), (void **) &server_name); if (server_name != NULL) { fprintf(sendmail, "X-Site-Origin: %s\n", server_name); } The problem I'm not sure how to declare server_name because I'm not really clear on what zend_hash_find() is expecting, and then if it will be compatible with the fprintf() statement. I've tried a few different things with the server_name declaration, but so far I haven't had any luck -- server_name always comes out blank. I guess I'm used to online API documentation that outlines all the functions, etc. I haven't been able to find anything yet with the Zend API that provides a complete list what everything does. I also tried using php_apache_getenv() and sapi_module.getenv(), but I am unclear of what I need to #include inside mail.c to get these to work. If I can just get past this hurdle, I think I will start understanding things much better. I'm really eager to learn as much C as possible, as I see it opening many doors for me, but I'm finding things to be very different from what I'm used to. If anyone has any recommendations on books for a good introduction to C, perhaps with some Unix focus, I'd be very happy to hear them.
