Replace the current regex to match with a new one.
- Parameters
-
regex The new regular expression to match cflags CFlags used to compile the regular expression; the defaults are case sensitive, extended RE.

Match a given string against the compiled regular expression, capturing the start and end positions of the matching string.
- Parameters
-
string The string to match match_start If the match succeeds, the starting index of the match in string match_end If the match succeeds, the index of the character in string following the last character of the match (remaining) WvString registers to capture substring matches as specified in the RE

◆ continuable_match() [2/2]

inline |
Match a given string against the compiled regular expression, capturing the start and end positions of the matching string.
- Parameters
-
string The string to match eflags EFlags that affect matching match_start If the match succeeds, the starting index of the match in string match_end If the match succeeds, the index of the character in string following the last character of the match (remaining) WvString registers to capture substring matches as specified in the RE
◆ isok()

By default, returns true if geterr() == 0.
Might be overridden so that isok() == false even though no error code has been specified.

◆ geterr()

If isok() is false, return the system error number corresponding to the error, -1 for a special error string (which you can obtain with errstr()) or 0 on end of file.
If isok() is true, returns an undefined number.
