qsort in standard library for DSC / MC56F800

Is the qsort() library function implemented as recursive function or not.

 

From MISRA 2012, Rule 21.9, page 170

 

The implementation of qsort is likely to be recursive and will therefore place unknown demands on stack resource. This is of concern in embedded systems as the stack is likely to be a fixed, often small size.

 

This rule raises a good question. I plan to use this function. As I want to be on the safe side I would like to have this question answered.
