AbnormalInputTimeoutHook is called for debugging purposes, whenever the session manager detects an application that is not processing user input correctly.

#define INCL_xxx
#include <os2.h>

HMQ     hmqCurrent;
PID     pid;
TID     tid;
BOOL    Processed;   /*  Success indicator. */

Processed = AbnormalInputTimeoutHook(hmqCurrent,
              pid, tid);
