函数名称：ptrace_event - possibly stop for a ptrace event notification*@event: %PTRACE_EVENT_* value to report*@message: value for %PTRACE_GETEVENTMSG to return* Check whether @event is enabled and, if so, report @event and @message* to the ptrace parent.

函数原型：static inline void ptrace_event(int event, unsigned long message)

返回类型：void

参数：

类型参数名称
intevent
unsigned longmessage
157  如果此条件成立可能性小(为编译器优化)(判断启用了跟踪)则
158  ptrace_message等于message
159  ptrace_notify((event << 8) | SIGTRAP)
160  否则如果event恒等于PTRACE_EVENT_EXEC则
162  如果ptrace按位与PT_PTRACED按位或SEIZE used, enable new behavior 的值的值恒等于PT_PTRACED则send_sig(SIGTRAP, 当前进程, 0)
