// Methods of bx_keymap_c :

// - loadKeymap(Bit32u convertStringToSymbol(const char*));
|
|
// loads the configuration specified keymap file if keymapping is enabled
|
|
// using convertStringToSymbol to convert strings to client constants
|
|
//
|

// - loadKeymap(Bit32u convertStringToSymbol(const char*), const char* filename);
|
|
// loads the specified keymap file
|

// using convertStringToSymbol to convert strings to client constants
|
|
//
|
|
// - isKeymapLoaded () returns true if the keymap contains any valid key
|
|
// entries.
|
|
//
|
|
// - convertStringToBXKey
|
|
// convert a null-terminate string to a BX_KEY code
