Hi there DJGPP lovers,

To start off with, I have 8Mb Physical RAM and run on a multi-config Windows
95 (ie, I don't start teh GUI).

I have smartdrv installed (2Mb), EMM386 NOEMS and CWSDPMI to run DJGPP
programs.

Now, the question...

I have a function that reports free physical RAM (cut and pasted from info
using RHIDE... it is in the go32_mem_info block section). This reports to me
that I have over 7000000 bytes free (it changes each time I run it,
depending on various things).

But when I try to allocate 62 blocks (each 64000 bytes), I run out of memory.
Shouldn't there be enough, and if not, shouldn't it start paging to disk? I
have 19Mb free on my Hd...

The actual sequence of calls is: (it's to load each frame of a FLI into a
seperate buffer)... BTW the size of the FLI file is < 40Kb

	* allocate a buffer for this frame (taken from frame_header.Size)
	* allocate 64000 bytes and store the frame
	* free the first buffer

	...	and do this 62 times.

Any ideas why I am running out of memory?

Thanks in advance

BRett
