Question

假设有一个核心转储，说路由器/交换机说运行vxworks。如何找到核心转储的任务？

我的猜测列出了任务，看看哪个处于运行状态，是吗？请告诉我。

您可以使用coreDumpLib.h中的coreDumpShow（）（vxWorks 6.9）。

-> coreDumpShow 0,1
NAME        IDX VALID   ERRNO      SIZE     CKSUM    TYPE        TASK
----------- --- ----- ---------- ---------- ----- ------------ ----------
vxcore1.z     1 Y            N/A 0x000ef05b OK    KERNEL_TASK  t1

Core Dump detailed information:
-------------------------------
Time:                   THU JAN 01 00:01:42 1970 (ticks = 6174)
Task:                   "t1" (0x611e0a20)
Process:                "(Kernel)" (0x6017a500)
Description:            fatal kernel task-level exception!
Exception number:       0xb
Program counter:        0x6003823e
Stack pointer:          0x604d3da8
Frame pointer:          0x604d3fb0

value = 0 = 0x0

您可能还想尝试查看coreDumpUtilLib：

coreDumpIsAvailable( ) - is a kernel core dump available for retrieval 
coreDumpNextGet( ) - get the next kernel core dump on device
coreDumpInfoGet( ) - get information on a kernel core dump
coreDumpOpen( ) - open an existing kernel core dump for retrieval
coreDumpClose( ) - close a kernel core dump
coreDumpRead( ) - read from a kernel core dump file
coreDumpCopy( ) - copy a kernel core dump to the given path
