Performs stream input and output operations on pseudo-random number distribution
ostas textual representation. The formatting flags and fill character of
ist. The formatting flags of
istare unchanged. The data must have been written using a stream with the same locale,
Traitstemplate parameters, otherwise the behavior is undefined. If bad input is encountered,
ist.setstate(std::ios::failbit)is called, which may throw
dis unchanged in that case.
These function templates are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when
std::uniform_int_distribution<ResultType> is an associated class of the arguments.
