TERMKEY_KEYNAME2SYM(3) | Library Functions Manual | TERMKEY_KEYNAME2SYM(3) |
NAME¶
termkey_keyname2sym - look up a symbolic key value for a string name
SYNOPSIS¶
#include <termkey.h> TermKeySym termkey_keyname2sym(TermKey *tk, const char *keyname);
Link with -ltermkey.
DESCRIPTION¶
termkey_keyname2sym() looks up the symbolic key value represented by the given string name. This is a case-sensitive comparison. If the given name is not found, TERMKEY_SYM_UNKNOWN is returned instead. This function is the inverse of termkey_get_keyname(3), and is a more specific form of termkey_lookup_keyname(3) which only recognises names as complete strings.
Because the key names are stored in an array indexed by the symbol number, this function has to perform a linear search of the names. Use of this function should be restricted to converting key names into symbolic values during a program's initialisation, so that efficient comparisons can be done while it is running.
RETURN VALUE¶
termkey_keyname2sym() returns a symbolic key constant, or TERMKEY_SYM_UNKNOWN.
