Hi! The io_* manuals says that we should use aio_context_t as type for aio handle. That is wrong as the functions are defined with io_context_t (libaio.h). Patch attached. The only oustanding issue is that manual for io_setup says that we must set the io_context_t to 0 before use. And as the io_context_t is defined as opaque type (and it's defined as pointer now) the only way to initalize it without warnigs is memset(&ctxp, 0, sizeof(ctxp));. Perhaps this is not needed at all, as the ctpx is passed to the syscall and then initalized in the kernel (at least I haven't seem any checks in the codepath). -- Cyril Hrubis chrubis@xxxxxxx
