Hello. In getunwind.2 first: otherwise, no data is copied, and the call succeeds, returning the size that would be needed to store the unwind data. and second: On success, getunwind returns the size of unwind table. As I understand size of unwind data > size of unwind table. What size really returned? -- Best Regards, Yuri Kozlov -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
