termkey_keycmp - compare two key events

termkey_keycmp()  compares  two  key  structures  and applies a total ordering, returning a value that is
       negative, zero, or  positive,  to  indicate  if  the  given  structures  are  increasing,  identical,  or
       decreasing.  Before  comparison,  copies  of  both  referenced  structures  are  taken, and canonicalised
       according to the rules for termkey_canonicalise(3).

       Two   structures   of   differing   type   are   ordered    TERMKEY_TYPE_UNICODE,    TERMKEY_TYPE_KEYSYM,
       TERMKEY_TYPE_FUNCTION, TERMKEY_TYPE_MOUSE. Unicode structures are ordered by codepoint, keysym structures
       are  ordered  by  keysym  number,  function  structures  are  ordered  by  function key number, and mouse
       structures are ordered opaquely by an unspecified but consistent  ordering.  Within  these  values,  keys
       different in modifier bits are ordered by the modifiers.

       termkey_keycmp - compare two key events

termkey_keycmp()  returns  an  integer greater than, equal to, or less than zero to indicate the relation
       between the two given key structures.
