Use .I XkbSetNames to change many names at the same time. For each bit set in .I which, XkbSetNames takes the corresponding value (or values in the case of arrays) from the keyboard description .I xkb and sends it to the server. The .I first_type and .I num_types arguments are used only if XkbKeyTypeNamesMask or XkbKTLevelNamesMask is set in .I which and specify a subset of the types for which the corresponding names are to be changed. If either or both of these mask bits are set but the specified types are illegal, .I XkbSetNames returns False and does not update any of the names specified in .I which. The specified types are illegal if .I xkb does not include a map component or if .I first_type and .I num_types specify types that are not defined in the keyboard description. .SH STRUCTURES .LP The XkbNameChangesRec allows applications to identify small modifications to the symbolic names and effectively reduces the amount of traffic sent to the server: .nf typedef struct _XkbNameChanges { unsigned int changed; /\&* name components that have changed */ unsigned char first_type; /\&* first key type with a new name */ unsigned char num_types; /\&* number of types with new names */ unsigned char first_lvl; /\&* first key type with new level names */ unsigned char num_lvls; /\&* number of key types with new level names */ unsigned char num_aliases; /\&* if key aliases changed, total number of key aliases */ unsigned char num_rg; /\&* if radio groups changed, total number of radio groups */ unsigned char first_key; /\&* first key with a new name */ unsigned char num_keys; /\&* number of keys with new names */ unsigned short changed_vmods; /\&* mask of virtual modifiers for which names have changed */ unsigned long changed_indicators; /\&* mask of indicators for which names were changed */ unsigned char changed_groups; /\&* mask of groups for which names were changed */ } XkbNameChangesRec, *XkbNameChangesPtr .fi The .I changed field specifies the name components that have changed and is the bitwise inclusive OR of the valid names mask bits defined in Table 1. The rest of the fields in the structure specify the ranges that have changed for the various kinds of symbolic names, as shown in Table 2. Xkb provides several functions that work with symbolic names. Each of these functions uses a mask to specify individual fields of the structures described above. These masks and their relationships to the fields in a keyboard description are shown in Table 1. .TS c s s s l l l l.
