XkbInitCanonicalKeyTypes(3) Set the definitions of the canonical key types in a


Status XkbInitCanonicalKeyTypes (XkbDescPtr xkb, unsigned int which, int keypadVMod);


- xkb
keyboard description containing client map to initialize
- which
mask of types to initialize
- keypadVMod
index of NumLock virtual modifier


XkbInitCanonicalKeyTypes initializes the first XkbNumRequiredTypes key types of the keyboard specified by the xkb parameter to their default values. The which parameter specifies what canonical key types to initialize and is a bitwise inclusive OR of the following masks: XkbOneLevelMask, XkbTwoLevelMask, XkbAlphabeticMask, and XkbKeypadMask. Only those canonical types specified by the which mask are initialized.

If XkbKeypadMask is set in the which parameter, XkbInitCanonicalKeyTypes looks up the NumLock named virtual modifier to determine which virtual modifier to use when initializing the KEYPAD key type. If the NumLock virtual modifier does not exist, XkbInitCanonicalKeyTypes creates it.

XkbInitCanonicalKeyTypes normally returns Success. It returns BadAccess if the Xkb extension has not been properly initialized, and BadAccess if the xkb parameter is not valid.


The XkbInitCanonicalKeyTypes funtion return Success if the Xkb extension has been properly initialized and the xkb parameter is valid.


The Xkb extension has not been properly initialized
