函数原型：enum siginfo_layout siginfo_layout(unsigned sig, int si_code)

返回类型：enum siginfo_layout

参数：

类型参数名称
unsignedsig
intsi_code
3149  layout等于SIL_KILL
3150  如果si_code大于sent by kill, sigsend, raise 且si_code小于sent by the kernel from somewhere 则
3151  如果sig小于ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(sig_sicodes)且si_code小于等于limit则
3153  layout等于layout
3155  如果sig恒等于SIGBUS且si_code大于等于hardware memory error consumed on a machine check: action required 且si_code小于等于hardware memory error detected in process but not consumed: action optional则layout等于SIL_FAULT_MCEERR
3158  否则如果sig恒等于SIGSEGV且si_code恒等于ailed address bound checks 则layout等于SIL_FAULT_BNDERR
3161  否则如果sig恒等于SIGSEGV且si_code恒等于ailed protection key checks 则layout等于SIL_FAULT_PKUERR
3165  否则如果si_code小于等于NSIGPOLL则layout等于SIL_POLL
3167  否则
3168  如果si_code恒等于sent by timer expiration 则layout等于SIL_TIMER
3170  否则如果si_code恒等于sent by queued SIGIO 则layout等于SIL_POLL
3172  否则如果si_code小于0则layout等于SIL_RT
3175  返回:layout
