std.mem

Memory utilities: thin wrappers over memcpy, memset, memcmp.

Functions

Function	Description
mem.copy(dest, src, n)	Copy n bytes from src to dest
mem.set(ptr, c, n)	Set n bytes at ptr to value c
mem.compare(a, b, n)	Compare n bytes; returns 0 if equal, <0 or >0 otherwise

Example

bring "std.mem";

extern craft malloc(size: usize) -> link void;
extern craft free(ptr: link void) -> void;

craft main() -> void {
    make buf: link void = malloc(16);
    mem.set(buf, 0, 16);
    make src: str = "hello";
    mem.copy(buf, src, 6);
    make cmp: i32 = mem.compare(buf, src, 5);
    free(buf);
    send;
}
