switches 0:0e018d759a2a 28
switches 0:0e018d759a2a 29 - the first can be used to detect the maximum heap usage at runtime. It is
switches 0:0e018d759a2a 30 activated by defining the MBED_HEAP_STATS_ENABLED macro.
switches 0:0e018d759a2a 31 - the second can be used to trace each memory call by automatically invoking
switches 0:0e018d759a2a 32 a callback on each memory operation (see hal/api/mbed_mem_trace.h). It is
switches 0:0e018d759a2a 33 activated by defining the MBED_MEM_TRACING_ENABLED macro.
switches 0:0e018d759a2a 34
switches 0:0e018d759a2a 35 Both tracers can be activated and deactivated in any combination. If both tracers
switches 0:0e018d759a2a 36 are active, the second one (MBED_MEM_TRACING_ENABLED) will trace the first one's
switches 0:0e018d759a2a 37 (MBED_HEAP_STATS_ENABLED) memory calls.*/
