Requires: [fmt, fmtend) shall be a valid range.
Effects: The function starts by evaluating err = ios_base::goodbit. It then enters a loop, reading zero or more characters from s at each iteration. Unless otherwise specified below, the loop terminates when the first of the following conditions holds:
The expression fmt == fmtend evaluates to true.
The expression err == ios_base::goodbit evaluates to false.
The expression s == end evaluates to true, in which case the function evaluates err = ios_base::eofbit | ios_base::failbit.
The next element of fmt is equal to '%', optionally followed by a modifier character, followed by a conversion specifier character, format, together forming a conversion specification valid for the ISO/IEC 9945 function strptime. If the number of elements in the range [fmt, fmtend) is not sufficient to unambiguously determine whether the conversion specification is complete and valid, the function evaluates err = ios_base::failbit. Otherwise, the function evaluates s = do_get(s, end, f, err, t, format, modifier), where the value of modifier is '\0' when the optional modifier is absent from the conversion specification. If err == ios_base::goodbit holds after the evaluation of the expression, the function increments fmt to point just past the end of the conversion specification and continues looping.
The expression isspace(*fmt, f.getloc()) evaluates to true, in which case the function first increments fmt until fmt == fmtend || !isspace(*fmt, f.getloc()) evaluates to true, then advances s until s == end || !isspace(*s, f.getloc()) is true, and finally resumes looping.
The next character read from s matches the element pointed to by fmt in a case-insensitive comparison, in which case the function evaluates ++fmt, ++s and continues looping. Otherwise, the function evaluates err = ios_base::failbit.
[ Note: The function uses the ctype<charT> facet installed in f's locale to determine valid whitespace characters. It is unspecified by what means the function performs case-insensitive comparison or whether multi-character sequences are considered while doing so. — end note ]
Returns: s.
