Determing heap used & free spacePosted by JC on July 1, 2007 Is there a method for determining the total heap free space? I have several tasks running, and I'd like to reduce the heap space to use the RAM for some buffers. Browsing the source code and the news groups, I haven't run across a mechanism to determine this. Does any code exist to cruise the heap and report heap metrics, such as largest available free block, number of blocks, total free space, etc? At the moment, I'm using the heap_2.c implementation of the heap manager. Thanks, --jc RE: Determing heap used & free spacePosted by JC on July 1, 2007 Naturally, after posting, a few more minutes searching found the post by Janusz for the vPortUsedMem() code. --jc
