I developed a small application using FreeRTOS. But I
have a question about FreeRTOS.

The vPortFree() function in the heap_1.c file has no
code. Then I look at the FreeRTOS web site. And the
heap_2.c and heap_3.c files have vPortFree() function.
So I can free RAM storage. But I couldn't find the
heap_2.c or heap_3.c files.

How can I get these files?

The files are contained in the download. Look in the source/portable/MemMang directory.

Regards.

Thanks
