explain the mem_assert macro to me

[manoj15]

I am tinkering around esp-adf and found this snippet of code

Code: Select all

    ESP_LOGI(TAG, "[3.0] Create audio pipeline for playback");
    audio_pipeline_cfg_t pipeline_cfg = DEFAULT_AUDIO_PIPELINE_CONFIG();
    pipeline = audio_pipeline_init(&pipeline_cfg);
    mem_assert(pipeline);

what is the mem_assert(piperline) line does ?

it's defined in audio_common.h
#define mem_assert(x)

can anyone explain ?

By default it doesn't do anything but seems intended for throwing an exception similar to ESP_ERROR_CHECK for debugging

[manoj15]

where's the statement if it's to throw some exception?

You have to add it. By default it is blank.
