Re: [Crash-utility] How to fire crash command from extension directly
----- Original Message -----
Hi Dave,
Thank you so much for responding to the query.
If its printing backtrace then calling back_trace() would suffice.
But I have few global structures that can be printed in crash by
just their name.
e.g. struct xyz object; Where its member is "int i"
Above declaration is global so in crash I can simply dump its
contents as below (provided object symbols are loaded in crash)
crash> object <ENTER>
object = {
i = 0;
}
So I want to achieve same thing via crash extension as I have too
many structures that I want to dump.
Any suggestions how it can be achieved ?
Get the address of "object" xyz structure with:
address = symbol_value("object");
and then either dump the complete structure with:
dump_struct("xyx", address, RADIX(16));
or just the "i" member with:
dump_struct_member("xyz.i", address, RADIX(16));
You can use RADIX(10) to dump non-pointer values in decimal, or pass 0
in the 3rd argument to utilize whatever the current hex/dec radix output
format is set.
