template<typename _CharT, typename _OutIter>

_OutIter std::time_put< _CharT, _OutIter >::do_put ( iter_type __s, ios_base & __io, char_type __fill, const tm * __tm, char __format, char __mod ) const

protectedvirtualinherited

Format and output a time or date.

This function formats the data in struct tm according to the provided format char and optional modifier. This function is a hook for derived classes to change the value returned.

See also

put() for more details.

Parameters

__s	The stream to write to.
__io	Source of locale.
__fill	char_type to use for padding.
__tm	Struct tm with date and time info to format.
__format	Format char.
__mod	Optional modifier char.

Returns

Iterator after writing.
