Hi! a question about processes

I'd like to read another process's whole memory, with my own program on either windows or linux.
I thought i could use fork, since i get the process id of the forked process and then, to make the forked process do execv with the application i want to read it's process. Could that work somehow?

I'll be very grateful for every direction

I'll check that out

cat /proc/<pid>maps
will get you your process mappings
Then you can use gdb's command dump to copy all/any of the mappings to the file.
