TERMKEY_KEYCMP(3) Library Functions Manual TERMKEY_KEYCMP(3) NAME termkey_keycmp - compare two key events SYNOPSIS #include <termkey.h> int termkey_keycmp(TermKey *tk, const TermKeyKey *key1, const TermKeyKey *key2); Link with -ltermkey. DESCRIPTION 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 compari- son, copies of both referenced structures are taken, and canonicalised ac- cording 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 or- dering. Within these values, keys different in modifier bits are ordered by the modifiers. RETURN VALUE termkey_keycmp() returns an integer greater than, equal to, or less than zero to indicate the relation between the two given key structures.
