the vmap struct is used to describe the virtual address space of
|
|
the target we are manipulating. The first entry is always the "exec"
|
|
file. Subsequent entries correspond to other objects that are
|
|
mapped into the address space of a process created from the "exec" file.
|
|
These are either in response to exec()ing the file, in which case all
|
|
shared libraries are loaded, or a "load" system call, followed by the
|
|
user's issuance of a "load" command. */
