termkey_lookup_keyname3
Look up a symbolic key value for a string name
Usage
#include <termkey.h>
char *termkey_lookup_keyname(TermKey *tk, const char *keyname,
TermKeySym *sym);
Link with -ltermkey.
Overview
termkey_lookup_keyname() looks up the symbolic key value represented by the given string name. This is a case-sensitive comparison. The symbolic value is written to the variable addressed by sym. This function is a more general form of termkey_keyname2sym(3) because it can recognise a symbolic key name within a longer string, returning a pointer to the remainder of the input after the key name.
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_lookup_keyname() returns a pointer to the first character after a recognised name, or NULL if the string does not begin with the name of a recognised symbolic key.
