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