        //DWORD Foa_AddrFun = RvaToFileOffset(pFileBuffer, *pFoa_AddressOfFunctions);
        return *pFoa_AddressOfFunctions;
    }
    

    验证执行效果:

    执行之前的要传入的参数:

    调用函数传入参数的相关代码

    VOID PrintFunctionAddrByNameAndOrdinals()
    {
        LPVOID pFileBuffer = NULL;
        DWORD FileBufferSize = 0;
        DWORD BaseName_FunctionAddr = 0;
        DWORD BaseOrdinals_FUnctionAddr = 0;
        char pFunctionName[] = "png_set_rows";
        
        //File-->FileBuffer
        FileBufferSize = ReadPEFile(FilePath_In,&pFileBuffer);
        if (FileBufferSize == 0 || !pFileBuffer)
        {
            printf("文件-->缓冲区失败
    ");
            return ;
        }
        printf("FileBufferSize: %#X 
    ",FileBufferSize);
        
        BaseName_FunctionAddr = GetFunctionAddrByName(pFileBuffer,pFunctionName);
        printf("GetFunctionAddrByName: %#X 
    ",BaseName_FunctionAddr);
    
        BaseOrdinals_FUnctionAddr = GetFunctionAddrByOrdinals(pFileBuffer,0x000000AE);
        printf("GetFunctionAddrByOrdinals: %#X 
    ",BaseOrdinals_FUnctionAddr);
        
        free(pFileBuffer);
    }
    

    执行结果:

    迷茫的人生,需要不断努力,才能看清远方模糊的志向!
