can anybody tell me if there is a way we can force a segfault with certain specific information in it. Forcing a segfault can be done through abort(), call. But i need something like abort(ptr), where ptr is a pointer that tells the actual memory where some corruption started.
thanks, Kapil Upadhayay
Your question is very unclear. Core dump contains a memory snapshot of your entire process, so it already contains the info you want it to contain.
如果你想更容易发现这种信息,那么你就能够引进一种全球性的信息,例如。
void *a_corrupt_ptr; // global
void some_func() {
...
if (the_pointer_has_been_corrupted(ptr)) {
a_corrupt_ptr = ptr;
abort();
}
然后在座标上查阅<代码>a_corrupt_ptr。
Or you can simply print the value before calling abort().
