I need to use Mongoose 3.0 for some reason. But, I am facing a problem
related to passing user_data. Looks like this Mongoose version provides the
facility to set user_data in main() when calling mg_start() but not when
event handler fn callback() gets called. Is there a separate field for that
or is there a separate way to do that? Am I missing something here?
typedef void * (*mg_callback_t)(enum mg_event event, struct
mg_connection *conn, const struct mg_request_info *request_info);
(gdb) p *conn->ctx->user_callback
$6 = {void *(enum mg_event, struct mg_connection *, const struct
mg_request_info *)} 0x406b18 <callback>
My requirement is to allocate user_data depending upon request data, which
is available only when event handler fn callback() gets called. Please let
me know how can I create and pass user data in event handler fn callback()?
*Program snippet*
static void *callback(enum mg_event event, struct mg_connection *conn,
const struct mg_request_info *request_info)
{
//since request_info is declared as const, I cannot do following
// request_info->user_data = "NEW_REQUEST_DATA";
}
int
main(void)
{
int cfd;
struct mg_context *ctx;
char *user_data = "MY_DATA";
ctx = mg_start(callback, user_data, options);
pause();
return 0;
}
*Mongoose 3.0 source code*
