die()

void die	(	const char *	fmt,
			...
	)

explain_re()

std::regex explain_re	(	explain_re_str	,
		std::regex_constants::nosubs|std::regex_constants::icase
	)

multi_reg_replace()

int multi_reg_replace	(	struct st_replace_regex *	r,
		char *	val,
		size_t *	len
	)

Execute all substitutions on val.

Parameters

[in]	val	Pointer to the character string to be used as input for the regex replace operation.
[in,out]	r	Pointer to the st_replace_regex structure which holds arguments and information for the command.
[in,out]	len	Pointer to variable holding length of input string.

Return values

True	If substituition was made.
False	If no substituition was made.

Note

r->buf points at the resulting buffer with all substitutions done. len points at length of resulting buffer. r->even_buf and r->odd_buf might have been reallocated. r->even_buf_len and r->odd_buf_len might have been changed.

opt_trace_re()

std::regex opt_trace_re	(	opt_trace_re_str	,
		std::regex_constants::nosubs|std::regex_constants::icase
	)

ps_re()

std::regex ps_re	(	ps_re_str	,
		std::regex_constants::nosubs|std::regex_constants::icase
	)

search_protocol_re()

int search_protocol_re	(	std::regex *	re,
		const char *	str
	)

Function to check if a protocol's regular expression matches the query string.

Parameters

re	Pointer to a precompiled regular expression.
str	Pointer to character string in which the pattern needs to be searched.

Return values

1	If the pattern is found.
0	If the pattern is not found.

sp_re()

std::regex sp_re	(	sp_re_str	,
		std::regex_constants::nosubs|std::regex_constants::icase
	)

view_re()

std::regex view_re	(	view_re_str	,
		std::regex_constants::nosubs|std::regex_constants::icase
	)
