Hello,
I wanted to save the whole context of the process, thats why I want
the access to each page allocated to the process of our interest. And
further I want to write all these pages on to swap.
The final objective is to save the context of a stopped process on
the swap and restore the context afterwards and resume the
process.Whatfunctions can be used to read/write to swap ? I have
succeeded
in accessing the vmspace through the 'struct proc' type pointer.
TIA.
Best regards,
Pranav
