Provided by: libx11-doc_1.6.4-3ubuntu0.4_all bug

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.

       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
