types - Common type aliases and geometric structs

Header: kernel/include/kernel/types.h

Provides a small set of type aliases and simple structs used throughout the kernel.

Type aliases

string

typedef char *string;

Alias for char *. Used in older parts of the codebase (e.g. the serial driver) as a semantic hint that the pointer points to a null-terminated C string.

Structs

Point

typedef struct {
    int32_t X, Y;
} Point;

A signed 2-D integer coordinate. Suitable for screen positions where negative values are meaningful (e.g. partially off-screen).

UPoint

typedef struct {
    uint32_t X, Y;
} UPoint;

An unsigned 2-D integer coordinate. Suitable for pixel or character-cell positions where coordinates are always non-negative.
