Defined in header <regex>
regex_error( std::regex_constants::error_type ecode );	(1)	(since C++11)
regex_error( const regex_error& other );	(2)	(since C++11)

1) Constructs a regex_error with a given ecode of type std::regex_constants::error_type.

2) Copy constructor. Initializes the contents with those of other. If *this and other both have dynamic type std::regex_error then std::strcmp(what(), other.what()) == 0.

Parameters

ecode	-	error code indicating the error raised in regular expression parsing
other	-	another regex_error object to copy
