Function drone_core::ffi::libc::calloc [−][src]
#[no_mangle]pub unsafe extern "C" fn calloc(nmemb: size_t, size: size_t) -> *mut c_void
Allocates memory for an array of nmemb
elements of size
bytes each and
returns a pointer to the allocated memory. The memory is set to zero. If
nmemb
or size
is 0, then it returns either NULL
, or a unique pointer
value that can later be successfully passed to free
.
