GPL, closed source, private, it's all good :) Detour Settings: bAutoReturn - If true, after hookfunc is called, the original function will be called with the original args - unless Ret(false) has been called bNoRegs - If true, detour does not modify any registers besides esp. Use for fastcalls / other funcs that take params in regs (evil msvc 2k5) (usually, detour will save ecx and reset it in Org for class funcs) bPolymorphic - If false the detour is a jmp. If true the detour is randomiezed and impliments a random number. These are alot bigger than 5 bytes iArgsOverride - Usually, the hookfunc is defined as identical to the function hooked in both args and calling convention. With this set, the stack will be modified after the hookfunc is called as if an stdcall with x args has been called. Useful if you have a stdcall func with like 10 args that you don't give a shit about (you'd otherwise have to have 10 junk args on your hookfunc) iBytesToOverwrite - Overrides the automatic reassembler.

/***************************** * Universal Detour Class * * v2.0 * ****************************** * By LanceVorgin * ****************************** * UNI owns all * *****************************/ /* All credit for CDetourDis goes to Micro$oft GG CB for the ByteArray idea - asshole :P License: I, LanceVorgin, allow you to use these classes in any of your projects under the following conditions: * My name appears in your readme and credits along with the fact that my CDetour was used * You do not take credit for CDetour That's all. GPL, closed source, private, it's all good :) Detour Settings: bAutoReturn - If true, after hookfunc is called, the original function will be called with the original args - unless Ret(false) has been called bNoRegs - If true, detour does not modify any registers besides esp. Use for fastcalls / other funcs that take params in regs (evil msvc 2k5) (usually, detour will save ecx and reset it in Org for class funcs) bPolymorphic - If false the detour is a jmp. If true the detour is randomiezed and impliments a random number. These are alot bigger than 5 bytes iArgsOverride - Usually, the hookfunc is defined as identical to the function hooked in both args and calling convention. With this set, the stack will be modified after the hookfunc is called as if an stdcall with x args has been called. Useful if you have a stdcall func with like 10 args that you don't give a shit about (you'd otherwise have to have 10 junk args on your hookfunc) iBytesToOverwrite - Overrides the automatic reassembler.

May be NULL in which // case DetourCopyInstruction is used to measure an instruction. // If not NULL then the source instruction is copied to the // destination instruction and any relative arguments are adjusted. // pbSrc: // Source address of the instruction. // ppbTarget: // Out parameter for any target instruction address pointed to by // the instruction. For example, a branch or a jump insruction has // a target, but a load or store instruction doesn't. A target is // another instruction that may be executed as a result of this // instruction. ppbTarget may be NULL. // plExtra: // Out parameter for the number of extra bytes needed by the // instruction to reach the target. For example, lExtra = 3 if the // instruction had an 8-bit relative offset, but needs a 32-bit // relative offset. // Returns: // Returns the address of the next instruction (following in the source) // instruction. By subtracting pbSrc from the return value, the caller // can determinte the size of the instruction copied. // Comments: // By following the pbTarget, the caller can follow alternate // instruction streams. However, it is not always possible to determine // the target based on static analysis. For example, the destination of // a jump relative to a register cannot be determined from just the // instruction stream. The output value, pbTarget, can have any of the // following outputs: // DETOUR_INSTRUCTION_TARGET_NONE: // The instruction has no targets. // DETOUR_INSTRUCTION_TARGET_DYNAMIC: // The instruction has a non-deterministic (dynamic) target. // (i.e. the jump is to an address held in a register.) // Address: The instruction has the specified target. // // When copying instructions, DetourCopyInstruction insures that any // targets remain constant. It does so by adjusting any IP relative // offsets. // PBYTE WINAPI DetourCopyInstructionEx(PBYTE pbDst, PBYTE pbSrc, PBYTE* ppbTarget, LONG* plExtra){ CDetourDis oDetourDisasm(ppbTarget, plExtra); return oDetourDisasm.CopyInstruction(pbDst, pbSrc); } PBYTE WINAPI DetourCopyInstruction(PBYTE pbDst, PBYTE pbSrc, PBYTE* ppbTarget){ CDetourDis oDetourDisasm(ppbTarget, NULL); return oDetourDisasm.CopyInstruction(pbDst, pbSrc); } /////////////////////////////////////////////////////////// Disassembler Code.
