stack memory warning for response

[thsmale]

$ ./server
addy.c:132:9: warning: address of stack memory associated with local variable 'response' returned [-Wreturn-stack-address]
        return response;
               ^~~~~~~~

This is not good. You are returning a pointer to an automatic (scoped) variable, which will be destroyed when the function returns. The pointer will be left pointing at a destroyed variable, which will almost certainly produce "strange" results (undefined behaviour).

You should be allocating the string with malloc (e.g. char *rtnPtr = malloc(length)), then freeing it later in main.

going to add a parameter, request will now accept request and response. this gives user the ability to specify the size of the request they wish to receive

[thsmale]

although char *response = request(struct Http options); than check if response is NULL is cleaner

[thsmale]

update example request in documentation to reflect these changes
