NAME
XkbAllocCompatMap − Allocate a new compatibility map if you do not already have one available
SYNOPSIS
|
Status XkbAllocCompatMap |
(XkbDescPtr xkb, unsigned int which, unsigned |
int num_si);
ARGUMENTS
|
− xkb |
keyboard description in which to allocate compat map |
− which
mask of compatibility map components to allocate
− num_si
number of symbol interpretations to allocate
DESCRIPTION
xkb specifies the keyboard description for which compatibility maps are to be allocated. The compatibility map is the compat field in this structure.
which specifies the compatibility map components to be allocated (see XkbGetCompatMap). which is an inclusive OR of the bits shown in Table 1.
num_si specifies the total number of entries to allocate in the symbol interpretation vector (xkb.compat.sym_interpret).
XkbAllocCompatMap returns Success if successful, BadMatch if xkb is NULL, or BadAlloc if errors are encountered when attempting to allocate storage.
STRUCTURES
typedef struct
{
KeySym sym; /∗ keysym of interest or NULL */
unsigned char flags; /∗ XkbSI_AutoRepeat,
XkbSI_LockingKey */
unsigned char match; /∗ specifies how mods is
interpreted */
unsigned char mods; /∗ modifier bits, correspond to
eight real modifiers */
unsigned char virtual_mod; /∗ 1 modifier to add to
key virtual mod map */
XkbAnyAction act; /∗ action to bind to symbol

} XkbSymInterpretRec,*XkbSymInterpretPtr;
DIAGNOSTICS
|
BadAlloc |
Unable to allocate storage | ||
|
BadMatch |
A compatible version of Xkb was not available in the server or an argument has correct type and range, but is otherwise invalid |

NOTES
Note that symbol interpretations in a compatibility map (the sym_interpret vector of XkbSymInterpretRec structures) are also allocated using this same function. To ensure that there is sufficient space in the symbol interpretation vector for entries to be added, use XkbAllocCompatMap specifying which as XkbSymInterpretMask and the number of free symbol interpretations needed in num_si.
