1. NAME

XkbFreeGeometry - Free an entire geometry

2. SYNOPSIS

void XkbFreeGeometry (XkbGeometryPtr geom , unsigned int which , Bool free_all );

3. ARGUMENTS

  • - geom
        geometry to be freed
  • - which
        mask of geometry components to be freed
  • - free_all
        True => the entire geometry is freed

4. DESCRIPTION

Xkb provides a number of functions to allocate and free subcomponents of a keyboard geometry. Use these functions to create or modify keyboard geometries. Note that these functions merely allocate space for the new element(s), and it is up to you to fill in the values explicitly in your code. These allocation functions increase sz_*but never touch num_*(unless there is an allocation failure, in which case they reset both sz_*and num_*to zero). These functions return Success if they succeed, BadAlloc if they are not able to allocate space, or BadValue if a parameter is not as expected. The values of whichand free_alldetermine how much of the specified geometry is freed. The valid values for whichare:

 
Sélectionnez
   #define   XkbGeomPropertiesMask      (1<<0)
    #define   XkbGeomColorsMask          (1<<1)
    #define   XkbGeomShapesMask          (1<<2)
    #define   XkbGeomSectionsMask        (1<<3)
    #define   XkbGeomDoodadsMask         (1<<4)
    #define   XkbGeomKeyAliasesMask      (1<<5)
    #define   XkbGeomAllMask             (0x3f)

If free_allis True, the entire geometry is freed regardless of the value of which.Otherwise, the portions of the geometry specified by whichare freed.

5. DIAGNOSTICS

BadAlloc

               Unable to allocate storage

BadValue

               An argument is out of range
