Memory.Manipulation

Library for memory manipulating, get regions, set rights, use pattern scan, calculate offsets, validate pointers and etc

Get regions

Mem.GetAllRegions() // All regions, even free
Mem.GetRegions(mbi => ...) // Regions adopting the condition in the arguments
Mem.GetAccesibleRegions() // Commited regions without Guard that has access flags
Mem.GetCommitedRegions() // All Commited regions
Mem.GetReadableRegions() // Regions available for reading
Mem.GetWriteableRegions() // Regions available for writing

Create pattern for signature scan

Mem.CreatePattern("0 2F 90 ?") // 00 2F 90 ??
Mem.CreatePattern("0 0x2F 90 ?????") // 00 2F 90 ??
Mem.CreatePattern("00 2F 90 .") // 00 2F 90 ??

Mem.CreatePattern(2d) // 40 00 00 00 00 00 00 00
// So work for all primitive types

Mem.CreatePattern([0, 0x2F, 0x90, null]) // 00 2F 90 ??

Signature scan

var regions = ...;
var pattern = ...;
var found = Mem.Scan(pattern, regions);

Pointer validating

var pointer = ...;
var isValid = Mem.IsValid(pointer); // Checks if the pointer is inside the commited region

Calculate offsets

var pointer = ...;
var shifted = Mem.CalcOffsets(pointer, 0, 8, 0x90, 0);
/*
  Alternative for:
    var shifted = *(nint*)(*(nint*)(*(nint*)(*(nint*)(pointer + 0) + 8) + 0x90) + 0);
*/
