## Description

Determines whether there is an exact match between the regular expression `re`, and all of the sequence `[begin, end)`.

Parameters: |
`begin` | The beginning of the sequence.
`end` | The end of the sequence.
`flags` | Optional match flags, used to control how the expression is matched against the sequence. (See `match_flag_type`.)
`re` | The regular expression object to use
`what` | The `match_results` struct into which the sub_matches will be written
Requires: | Type `BidiIter` meets the requirements of a Bidirectional Iterator (24.1.4). `[begin,end)` denotes a valid iterator range.
Returns: | `true` if a match is found, `false` otherwise
Throws: | \c
