guess: If your DLL is actually asking for a filename and opens it with
standard file i/o routines then you are pretty much without options.
However more generally what you want as far as reading from memory can be
certainly be done even though I haven't actually done it - having used
TFileStream stuff a lot with great success I notice there are lots of similar
routines that read and write memory streams as well - see
TMemoryStream.</SPAN></FONT></DIV>

<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=840305423-07072006>If you
were on linux/Unix there would be other options as well, as the memory (and
everything else as well) is part of the filesystem.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2>I doubt this is possible but I thought I would
ask anyway.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have a 3rd party DLL which opens a file
that I specify. Specially it is an audio decoder plugin which
decodes MP3 to PCM.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What I would like to do is use
this plugin to access a memory location which contains MP3 data instead
of a file.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is it possible to set up something in
Windows where you specify a filename but actually accesses memory
instead.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This will be used with encrypted mp3
files so they are not accessible to anyone to steal for their own use. I
am currently opening the file, decrypting, and then saving a
temporary file to disk. But this has 2 disadvantages. It is very
slow, so lots of latency between asking a track to play and hearing it.
And also, while the file is decrypted on disk, someone can steal
it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The DLL cannot be modified. Is there any
solution?</FONT></DIV>
