## `stdio` module
|
|
|
|
The `stdio` module automatically imports the `string` module.
|
|
It requires an implementation of `void putchar(byte a)` and therefore works only on targets with console output.
|
|
|
|
#### `void putstr(pointer str, byte len)`
|
|
|
|
Prints a string of length `len` located at address `str`.
|
|
|
|
#### `void putstrz(pointer str)`
|
|
|
|
Prints a null-terminated string located at address `str`.
|
|
If the string is longer than 255 bytes, then the behaviour is undefined (might even crash).
|
|
|
|
## `string` module
|
|
|
|
#### `byte strzlen(pointer str)`
|
|
|
|
Calculates the length of a null-terminated string.
|
|
If the string is longer than 255 bytes, then the behaviour is undefined (might even crash).
|
|
|
|
## `mouse` module
|
|
|
|
The `mouse` module automatically imports the `x_coord` module.
|
|
|
|
The module contains global variables representing the state of the mouse.
|
|
If the program is not using any mouse driver, the state of these variables is undefined.
|
|
|
|
#### `x_coord mouse_x`
|
|
|
|
Mouse X position.
|
|
|
|
#### `byte mouse_y`
|
|
|
|
Mouse Y position.
|
|
|
|
#### `byte mouse_lbm`
|
|
|
|
1 if the left mouse button is being pressed, 0 otherwise
|
|
|
|
#### `byte mouse_rbm`
|
|
|
|
1 if the right mouse button is being pressed, 0 otherwise
|
|
|
|
## `x_coord` module
|
|
|
|
#### `alias x_coord`
|
|
|
|
The type for representing horizontal screen coordinates.
|
|
It's `byte` if the screen is 256 pixels wide or less,
|
|
or `word` if the screen is more that 256 pixels wide. |
