*Preconditions*: [fmt, fmtend) is a valid range[.](#7.sentence-1)

*Effects*: The function starts by evaluating err = ios_base​::​goodbit[.](#8.sentence-1)

It then enters a loop,
reading zero or more characters from s at each iteration[.](#8.sentence-2)

Unless otherwise specified below,
the loop terminates when the first of the following conditions holds:

- [(8.1)](#8.1)

  The expression fmt == fmtend evaluates to true[.](#8.1.sentence-1)

- [(8.2)](#8.2)

  The expression err == ios_base​::​goodbit evaluates to false[.](#8.2.sentence-1)

- [(8.3)](#8.3)

  The expression s == end evaluates to true,
in which case
the function evaluates err = ios_base​::​eofbit | ios_base​::​failbit[.](#8.3.sentence-1)

- [(8.4)](#8.4)

  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 POSIX function strptime[.](#8.4.sentence-1)
  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[.](#8.4.sentence-2)
  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[.](#8.4.sentence-3)
  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[.](#8.4.sentence-4)

- [(8.5)](#8.5)

  The expression isspace(*fmt, f.getloc()) evaluates to true,
in which case the function first increments fmt untilfmt == fmtend || !isspace(*fmt, f.getloc()) evaluates to true,
then advances s until s == end || !isspace(*s, f.getloc()) is true, and
finally resumes looping[.](#8.5.sentence-1)

- [(8.6)](#8.6)

  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[.](#8.6.sentence-1)
  Otherwise, the function evaluates err = ios_base​::​failbit[.](#8.6.sentence-2)

[*Note [1](#note-1)*:

The function uses the ctype<charT> facet
installed in f's locale
to determine valid whitespace characters[.](#9.sentence-1)

It is unspecified
by what means the function performs case-insensitive comparison or
whether multi-character sequences are considered while doing so[.](#9.sentence-2)
