* This is an example of how the file header is changed. "Shoff" is
|
||||
* the section header offset within the file. Since that table is
|
||||
* after the new .data section, it is moved. "Shnum" is the number of
|
||||
* sections, which we increment.
|
||||
*
|
||||
* "Phoff" is the file offset to the program header. "Phentsize" and
|
||||
* "Shentsz" are the program and section header entries sizes respectively.
|
||||
* These can be larger than the apparent struct sizes.
