group-onsemi 0:098463de4c5d 27 /* There are two memory tracers in mbed OS:
group-onsemi 0:098463de4c5d 28
group-onsemi 0:098463de4c5d 29 - the first can be used to detect the maximum heap usage at runtime. It is
group-onsemi 0:098463de4c5d 30 activated by defining the MBED_HEAP_STATS_ENABLED macro.
group-onsemi 0:098463de4c5d 31 - the second can be used to trace each memory call by automatically invoking
group-onsemi 0:098463de4c5d 32 a callback on each memory operation (see hal/api/mbed_mem_trace.h). It is
group-onsemi 0:098463de4c5d 33 activated by defining the MBED_MEM_TRACING_ENABLED macro.
group-onsemi 0:098463de4c5d 34
group-onsemi 0:098463de4c5d 35 Both tracers can be activated and deactivated in any combination. If both tracers
group-onsemi 0:098463de4c5d 36 are active, the second one (MBED_MEM_TRACING_ENABLED) will trace the first one's
group-onsemi 0:098463de4c5d 37 (MBED_HEAP_STATS_ENABLED) memory calls.*/
