Method c_calloc

The C `calloc` function. `calloc` allocates storage sufficient to hold `nmemb` elements of size `size` and returns a pointer to it. The allocated memory is aligned to `MIN_ALIGN`. The memory is initialized to zero. If there is insufficient space to perform the allocation, `errno` is set to `ENOMEM` and the return value is `NULL`. # Platform-specific behavior On Linux, if either `size` or `nmemb

(&self, nmemb: size_t, size: size_t)
