// Template functions used by time_get
// Matching input against a list of names
// Alphabetic input of the names of months and the names
// of weekdays requires matching input against a list of names.
// We use a simple generic algorithm to accomplish this. This
// algorithm is not very efficient, especially for longer lists
// of names, but it probably does not matter for the initial
// implementation and it may never matter, since we do not expect
// this kind of input to be used very often. The algorithm
// could be improved fairly simply by creating a new list of
// names still in the running at each iteration. A more sophisticated
// approach would be to build a trie to do the matching.
//
// We compare each character of the input to the corresponding
// character of each name on the list that has not been eliminated,
// either because every character in the name has already been
// matched, or because some character has not been matched. We
// continue only as long as there are some names that have not been
// eliminated.
// We do not really need a random access iterator (a forward iterator
// would do), but the extra generality makes the notation clumsier,
// and we don't really need it.
// We can recognize a failed match by the fact that the second
// component of the return value will be __name_end.
#define _MAXNAMES 64
#define _MAX_NAME_LENGTH 64
// Both time_get and time_put need a structure of type _Time_Info
// to provide names and abbreviated names for months and days,
// as well as the am/pm designator. The month and weekday tables
// have the all the abbreviated names before all the full names.
// The _Time_Info tables are initialized using the non-template
// function _Init_timeinfo, which has two overloadings: one
// with a single reference parameter for the table to be initialized,
// and one with a second _Locale_time * parameter. The first form
// is called by the default constructor and the second by a special
// constructor invoked from the _byname subclass constructor to
// construct the base class.
