jkr, thank you for the link!<br />
<br />
How can I create named memory object in the driver (similar call to CreateFileMapping)?<br />
Can I use the mapped view of this section as fast as the buffer allocated by ExAllocatePool?<br />
(Note: the size of the buffer in question can be &gt;50Mb. I read somewhere that using file mapping object for large buffers may degrade the system performance.)<br />
<br />
Instead of file mapping can I use ExAllocatePool, MmProbeAndLockPages, MmMapLockedPages, etc. If such a sequence can work, what steps would it consist of exactly (I haven't used these memory management functions before)?<br />

<div class="content wysiwyg-content">
I have a kernel mode driver (actually a graphics miniport driver) that allocates a buffer by calling ExAllocatePool(PagedPoolCa<wbr />cheAligned<wbr />,NumberOfB<wbr />ytes).<br />
Is there a way to make this buffer available for an application?

Map to user space

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
