Function regex_search

boost::xpressive::regex_search — Determines whether there is some sub-sequence within [begin,end) that matches the regular expression re.

Description

Determines whether there is some sub-sequence within [begin,end) that matches the regular expression re.

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:

Types BidiIter and OtherBidiIter meet the requirements of a Bidirectional Iterator (24.1.4).

OtherBidiIter is convertible to BidiIter.

[begin,end) denotes a valid iterator range.

Returns:

true if a match is found, false otherwise

Throws: regex_error on stack exhaustion
