XkbAllocCompatMap(3) XKB FUNCTIONS XkbAllocCompatMap(3)
NAME
XkbAllocCompatMap - Allocate a new compatibility map if you do not al-
ready 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.
Table 1 Compatibility Map Component Masks
───────────────────────────────────────────────────────────────
Mask Value Affecting
───────────────────────────────────────────────────────────────
XkbSymInterpMask (1<<0) Symbol interpretations
XkbGroupCompatMask (1<<1) Group maps
XkbAllCompatMask (0x3) All compatibility map components
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 position on key */
} 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_inter-
pret 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 XkbAllocCom-
patMap specifying which as XkbSymInterpretMask and the number of free
symbol interpretations needed in num_si.
