handle

( n.)

   1.  [from CB slang] An electronic pseudonym; a nom de guerre intended
   to conceal the user's true identity. Network and BBS handles function
   as the same sort of simultaneous concealment and display one finds on
   Citizen's  Band  radio,  from  which  the  term  was  adopted. Use of
   grandiose  handles  is  characteristic  of {warez d00dz}, {cracker}s,
   {weenie}s,  {spod}s,  and  other  lower  forms  of network life; true
   hackers   travel  on  their  own  reputations  rather  than  invented
   legendry. Compare {nick}, {screen name}.

   2.  A  {magic cookie}, often in the form of a numeric index into some
   array  somewhere,  through  which you can manipulate an object like a
   file or window. The form file handle is especially common.

   3.  [Mac] A pointer to a pointer to dynamically-allocated memory; the
   extra  level  of  indirection allows on-the-fly memory compaction (to
   cut  down  on  fragmentation)  or aging out of unused resources, with
   minimal impact on the (possibly multiple) parts of the larger program
   containing  references  to  the  allocated memory. Compare {snap} (to
   snap  a  handle  would  defeat its purpose); see also {aliasing bug},
   {dangling pointer}.
