NAME
XkbAllocNames - Allocate symbolic names structures SYNOPSIS
Status XkbAllocNames (XkbDescPtr xkb, unsigned int which, int num_rg, int num_key_aliases); ARGUMENTS
- xkb keyboard description for which names are to be allocated - which mask of names to be allocated - num_rg total number of radio group names needed - num_key_aliases total number of key aliases needed DESCRIPTION
Most applications do not need to directly allocate symbolic names structures. Do not allocate a names structure directly using malloc or Xmalloc if your application changes the number of key aliases or radio groups or constructs a symbolic names structure without loading the necessary components from the X server. Instead use XkbAllocNames. XkbAllocNames can return BadAlloc, BadMatch, and BadValue errors. The which parameter is the bitwise inclusive OR of the valid names mask bits defined in Table 1. Table 1 Symbolic Names Masks --------------------------------------------------------------------------------- Mask Bit Value Keyboard Field Component --------------------------------------------------------------------------------- XkbKeycodesNameMask (1<<0) Xkb->names keycodes XkbGeometryNameMask (1<<1) Xkb->names geometry XkbSymbolsNameMask (1<<2) Xkb->names symbols XkbPhysSymbolsNameMask (1<<3) Xkb->names phys_symbols XkbTypesNameMask (1<<4) Xkb->names type XkbCompatNameMask (1<<5) Xkb->names compat XkbKeyTypeNamesMask (1<<6) Xkb->map type[*].name XkbKTLevelNamesMask (1<<7) Xkb->map type[*].lvl_names[*] XkbIndicatorNamesMask (1<<8) Xkb->names indicators[*] XkbKeyNamesMask (1<<9) Xkb->names keys[*], num_keys XkbKeyAliasesMask (1<<10) Xkb->names key_aliases[*], num_key_aliases XkbVirtualModNamesMask (1<<11) Xkb->names vmods[*] XkbGroupNamesMask (1<<12) Xkb->names groups[*] XkbRGNamesMask (1<<13) Xkb->names radio_groups[*], num_rg XkbComponentNamesMask (0x3f) Xkb->names keycodes, geometry, symbols, physical symbols, types, and compatibility map XkbAllNamesMask (0x3fff) Xkb->names all name components Do not free symbolic names structures directly using free or XFree. Use XkbFreeNames instead. 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 BadValue An argument is out of range SEE ALSO

NAME
XkbFreeNames - Free symbolic names structures SYNOPSIS
void XkbFreeNames (XkbDescPtr xkb, unsigned int which, Bool free_map); ARGUMENTS
- xkb keyboard description for which names are to be freed - which mask of names components to be freed - free_map True => XkbNamesRec structure itself should be freed DESCRIPTION
Do not free symbolic names structures directly using free or XFree. Use XkbFreeNames instead. The which parameter is the bitwise inclusive OR of the valid names mask bits defined in Table 1. 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.
