HyperDbgAssemble()

BOOLEAN HyperDbgAssemble	(	const CHAR *	AssemblyCode,
		UINT64	StartAddress,
		PVOID	BufferToStoreAssembledData,
		UINT32	BufferSize )

Assembler function.

Parameters

AssemblyCode	The assembly code
StartAddress	The start address of the assembly code
BufferToStoreAssembledData	The buffer to store the assembled data
BufferSize	The size of the buffer

Returns

BOOLEAN Returns true if it was successful

{
    AssembleData AssembleData;
 
    //
    // Convert assembly code to string
    //
    std::string AsmCode = AssemblyCode;
 
    AssembleData.AsmRaw = AsmCode;
    AssembleData.ParseAssemblyData();
 
    if (AssembleData.Assemble(StartAddress))
    {
        return FALSE;
    }
    else
    {
        if (AssembleData.BytesCount > BufferSize)
        {
            return FALSE;
        }
 
        //
        // Copy the assembled data to the buffer
        //
        memcpy(BufferToStoreAssembledData, AssembleData.EncodedBytes, AssembleData.BytesCount);
 
        return TRUE;
    }
}

HyperDbgAssembleGetLength()

BOOLEAN HyperDbgAssembleGetLength	(	const CHAR *	AssemblyCode,
		UINT64	StartAddress,
		UINT32 *	Length )

Assembler function.

Parameters

AssemblyCode	The assembly code
StartAddress	The start address of the assembly code
Length	The length of the assembly code in bytes (to be returned)

Returns

BOOLEAN Returns true if it was successful

{
    AssembleData AssembleData;
 
    //
    // Convert assembly code to string
    //
    std::string AsmCode = AssemblyCode;
 
    AssembleData.AsmRaw = AsmCode;
    AssembleData.ParseAssemblyData();
 
    if (AssembleData.Assemble(StartAddress))
    {
        return FALSE;
    }
    else
    {
        //
        // Get the BytesCount
        //
        *Length = (UINT32)AssembleData.BytesCount;
 
        return TRUE;
    }
