So when i map my memory block in a file map in my windows programm , my Dos based programm can open it with Fopen C command for example ? <br />
Anyway , is there a way to allow low based memory in visual C++ (with segment and offset) ? or a better way to share memory block than using file mapping ? <br />

<div class="content wysiwyg-content">
As I read in MSDN : <br />
<br />
Applications requiring shared memory for other purposes must use file-mapping objects. Multiple processes can map a view of the same file-mapping object to provide named shared memory. For more information, see File Mapping.<br />
<br />
Question 1 : can i access it from a Dos based Programm if i use FileMapping ?<br />
<br />
Question 2: If not ? How can i share a block of memory between a dos programm i made and a Windows Programm i made ?<br />
<br />
Thanx Very much ..!<br />

how to share memory block from a windows programm and a dos programm

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
