Function mi_mallocn 

pub unsafe extern "C" fn mi_mallocn(
    count: usize,
    size: usize,
) -> *mut c_void

Allocate count items of size length each.

Returns null if count * size overflows or on out-of-memory, otherwise returns the same as mi_malloc(count * size). Equivalent to mi_calloc, but returns uninitialized (and not zeroed) bytes.
