vipinranka 12:9a20164dcc47 27 /* There are two memory tracers in mbed OS:
vipinranka 12:9a20164dcc47 28
vipinranka 12:9a20164dcc47 29 - the first can be used to detect the maximum heap usage at runtime. It is
vipinranka 12:9a20164dcc47 30 activated by defining the MBED_HEAP_STATS_ENABLED macro.
vipinranka 12:9a20164dcc47 31 - the second can be used to trace each memory call by automatically invoking
vipinranka 12:9a20164dcc47 32 a callback on each memory operation (see hal/api/mbed_mem_trace.h). It is
vipinranka 12:9a20164dcc47 33 activated by defining the MBED_MEM_TRACING_ENABLED macro.
vipinranka 12:9a20164dcc47 34
vipinranka 12:9a20164dcc47 35 Both tracers can be activated and deactivated in any combination. If both tracers
vipinranka 12:9a20164dcc47 36 are active, the second one (MBED_MEM_TRACING_ENABLED) will trace the first one's
vipinranka 12:9a20164dcc47 37 (MBED_HEAP_STATS_ENABLED) memory calls.*/
