The first thing to note is that the lower layers may send up less ++events than the user requested, but only if that was a result of a pen release. ++Next, your module should send up just as many events as the user requested in ++nr. If your module is one that consumes events, such as variance, then you ++loop on the read from the lower layers, and only send the events up when ++1) you have the number of events requested by the user, or 2) one of the events ++from the lower layers was a pen release. ++ + + Module Parameters + ================= +--- tslib/src/ts_read_raw.c~multievent ++++ tslib/src/ts_read_raw.c +@@ -14,10 +14,10 @@ + * + * Read raw pressure, x, y, and timestamp from a touchscreen device. + */ ++ + #include "config.h" + + #include +- + #include + #ifdef HAVE_UNISTD_H + #include +@@ -25,79 +25,27 @@ + #include + #include + +-#ifdef USE_INPUT_API +-#include +-#else +-struct ts_event { /* Used in UCB1x00 style touchscreens (the default) */ +- unsigned short pressure;
