dkato 0:f782d9c66c49 27 /* There are two memory tracers in mbed OS:
dkato 0:f782d9c66c49 28
dkato 0:f782d9c66c49 29 - the first can be used to detect the maximum heap usage at runtime. It is
dkato 0:f782d9c66c49 30 activated by defining the MBED_HEAP_STATS_ENABLED macro.
dkato 0:f782d9c66c49 31 - the second can be used to trace each memory call by automatically invoking
dkato 0:f782d9c66c49 32 a callback on each memory operation (see hal/api/mbed_mem_trace.h). It is
dkato 0:f782d9c66c49 33 activated by defining the MBED_MEM_TRACING_ENABLED macro.
dkato 0:f782d9c66c49 34
dkato 0:f782d9c66c49 35 Both tracers can be activated and deactivated in any combination. If both tracers
dkato 0:f782d9c66c49 36 are active, the second one (MBED_MEM_TRACING_ENABLED) will trace the first one's
dkato 0:f782d9c66c49 37 (MBED_HEAP_STATS_ENABLED) memory calls.*/
