mg_queue_prinf() sets wrong Content-Length / queue size.
T-a-n-d-E-m opened this issue · comments
The following snippet sets the queue length to 2 (the length of the format string) not the expected 13 (the length of the final string generated).
// Create the queue and init it ...
char buffer[1024];
mg_queue queue;
mg_queue_init(&queue, buffer, 1024);
// ... later on
const char* str = "Hello, World!";
mg_queue_printf(&queue, "%s", str);
I'm using release 7.12.
