Keeping these up-to-date is just super tedious and they don't really fulfill any purpose these days.

// These structures represent the header(s) of an NT image.
|
|
//
|
|
// There are two ways to read the image:
|
|
// - Loading the executable/library in memory and then reading the content at
|
|
// the beginning.
|
|
// - Reading the process' memory at the beginning (base address).
|
|
// In the case of a loaded library, its header(s) can be found at its load
|
|
// (base) address.
|
|
//
|
|
// By reading the header(s) we can gather useful info regarding the process,
|
|
// such as the architecture and, in the case of a library, the address of an
|
|
// exported symbol.
