ESP8266 Community Forum

- Fri Feb 06, 2015 8:38 pm #9150 Hello, my name is Daniel and I'm new here. I started programming the ESP8266 with the SDK a few weeks ago and now I'm at the point where I need dynamic memory. I found out, that there are four functions to manage dynamic memory:
os_malloc
os_realloc
os_zalloc
os_free

malloc, realloc and free are clear, but what is zalloc for?

Thanks and best regards,
Dani

zalloc == malloc + zeroize allocated memory.

It does similar thing, but it has different signature: void *os_zalloc(size_t).
