+.LP
+.I xkb
+specifies the keyboard description for which compatibility maps are to be allocated. The compatibility map is the
+.I compat
+field in this structure.
+
+.I which
+specifies the compatibility map components to be allocated (see XkbGetCompatMap).
+.I which
+is an inclusive OR of the bits shown in Table 1.

+XkbSymInterpMask (1<<0) Symbol interpretations
+XkbGroupCompatMask (1<<1) Group maps
+XkbAllCompatMask (0x3) All compatibility map components
+.TE
+
+.I num_si
+specifies the total number of entries to allocate in the symbol interpretation vector
+.I (xkb.compat.sym_interpret).
+
+.I XkbAllocCompatMap
+returns Success if successful, BadMatch if
+.I xkb
+is NULL, or BadAlloc if errors are encountered when attempting to allocate storage.

+.B BadMatch
+A compatible version of Xkb was not available in the server or an argument has correct type and range, but is otherwise invalid

+.SH NOTES
+.LP
+Note that symbol interpretations in a compatibility map (the
+.I 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
+.I XkbAllocCompatMap
+specifying
+.I which
+as XkbSymInterpretMask and the number of free symbol interpretations needed in
+.I num_si.
