Monitoring calloc

MikeH

One of my calls to "calloc" is failing (returns zero). Is there a way in CCS4 to see why it is failing to allocate memory?

Mike,

calloc() only fails if there is not enough heap to hold the allocated size. This particular API is really easy to run out of memory due to its parameters. Please check the post below that talks about a similar issue.

There is no easy way to reliably report heap usage, but some suggestions can be found in the post below:

Hope this helps,

Rafael

In addition to Rafael's comments, if you are using DSP/BIOS you can open up the Kernel Object Viewer just before calling calloc() to find out how much of that heap is available. KOV polls a lot of statistical information including largest contiguous block of free memory in each heap.

Thanks Tim. I have not yet tackled DSP/BIOS, but I will give it a try at some point.
