Methods

ApplyDetour(IntPtr, IntPtr, Architecture, Int32)

Improve this Doc View Source

Writes a detour on to redirect to .

Declaration

public static void ApplyDetour(IntPtr functionPtr, IntPtr detourPtr, Architecture architecture, int minimumLength = 0)

Parameters

Type	Name	Description
`System.IntPtr`	`functionPtr`	The pointer to the function to apply the detour to.
`System.IntPtr`	`detourPtr`	The pointer to the function to redirect to.
`System.Runtime.InteropServices.Architecture`	`architecture`	The architecture of the current platform.
`System.Int32`	`minimumLength`	The minimum amount of length that the detour should consume. If the generated redirect is smaller than this, the remaining space is padded with NOPs.

CreateTrampolineFromFunction(Byte[], IntPtr, IntPtr, Int32, Architecture, out Int32, out Int32)

Reads assembly from (at least bytes), and writes it to plus a jmp to continue execution.

Declaration

public static void CreateTrampolineFromFunction(byte[] instructionBuffer, IntPtr functionPtr, IntPtr trampolinePtr, int minimumTrampolineLength, Architecture arch, out int trampolineLength, out int jmpLength)

Parameters

Type	Name	Description
`System.Byte[]`	`instructionBuffer`	The buffer to copy assembly from.
`System.IntPtr`	`functionPtr`	The pointer to the function to copy assembly from.
`System.IntPtr`	`trampolinePtr`	The pointer to write the trampoline assembly to.
`System.Int32`	`minimumTrampolineLength`	Copies at least this many bytes of assembly from .
`System.Runtime.InteropServices.Architecture`	`arch`	The architecture of the current platform.
`System.Int32`	`trampolineLength`	Returns the total length of the trampoline, in bytes.
`System.Int32`	`jmpLength`	Returns the length of the jmp at the end of the trampoline, in bytes.
