SetPattern()

bool CRegex::SetPattern	(	const char *	pattern,
		int	cflags = REG_EXTENDED
	)

Set and compile a search pattern.

Parameters

pattern	The pattern (or NULL to not match anything)
cflags	Bit-wise OR of the following flags (see regexp(3)): REG_EXTENDED: Use POSIX Extended Regular Expression syntax REG_ICASE: Ignore case REG_NOSUB: Do not report position of matches REG_NEWLINE: Match-any-character operators don't match a newline

Returns

'true' on success, 'false' on failure

Match()

bool CRegex::Match	(	const char *	s,
		int	eflags = 0,
		size_t	maxMatches = 0,
		regmatch_t *	retMatchList = NULL
	)

Perform a regular expression search.

Parameters

s	The string to be analysed
eflags	Bit-wise OR of the following flags (see regexp(3)): REG_NOTBOL: The match-beginning-of-line operator always fails to match REG_NOTEOL: The match-end-of-line operator always fails
maxMatches	At most this many matches are returned
retMatchList	If not NULL, the list of matches is written into *retMatchList (see regexp(3))

Returns

true if and only if the regular expression matched. If no pattern has been set before, false is returned.
