Hi I try to write a python backend for pamcan-g2, for that I should write a callback for *trans_cb_conv
In python I've write : trans_cb_event = CFUNCTYPE(ctypes.c_char_p,ctypes.c_void_p,POINTER(ctypes.c_int) ... def fpm_trans_conv(event,pkg,response): foo... response=1 and for call the callback if trans_init(pm_trans,flags, trans_cb_event(fpm_progress_event), trans_cb_conv(fpm_trans_conv), None) == -1 : foo... Into libpacman response is a C int pointer : ... QUESTION(trans, PM_TRANS_CONV_LOCAL_UPTODATE, local, NULL, NULL, &resp); ... but resp=0 howto pass response by reference instead by value ?
