Hi guys,
Is is safe to call driver_realloc (http://www.erlang.org/doc/man/erl_driver.html#driver_realloc) with a null pointer:
ErlDrvBinary *ptr = NULL;
[...]
ptr = driver_realloc(ptr, len);
assert(ptr);
The doc says it's simply a wrapper around "realloc" and my code seems to work well.
The first call is simply a call to "malloc" as the pointer is null, right?
Can you confirm (OTP) guys?
Regards,
Zabrane
