// Methods of bx_keymap_c :
//
// - loadKeymap(const char *prefix, 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
//
// - findHostKey(Bit32u key)
// - findAsciiChar(Bit8u ch)
// Each of these methods returns a pointer to a BXKeyEntry structure
// corresponding to a key. findHostKey() finds an entry whose hostKey
// value matches the target value, and findAsciiChar() finds an entry
// whose ASCII code matches the search value.
// In case of unknown symbol
#define BX_KEYMAP_UNKNOWN 0xFFFFFFFF
