Function Documentation

◆ printable()

static bool printable ( int ch )

inlinestatic

Thinking in non-internationalized US-ASCII (per the DNS spec), is this character visible and not a space when printed?

Note: This is a helper function for rip_ns_name_ntop()

Parameters

ch	Character to check.

Returns: Returns true if character is visible when printed, otherwise returns false.

Here is the caller graph for this function:

◆ rip_dn_find()

static int rip_dn_find	(	const unsigned char *	domain,
		const unsigned char *	msg,
		const unsigned char **	dnptrs,
		const unsigned char **	lastdnptr
	)

static

Search for the counted-label name in an array of compressed names.

DNPTRS is the pointer to the first name on the list, not the pointer to the start of the message.

Note: This is a helper function for rip_ns_name_pack().

Parameters

domain	Name to search for.
msg	DNS message to search name in.
dnptrs	See rip_ns_name_put().
lastdnptr	See rip_ns_name_put().

Returns: Returns the offset from MSG if found, or -1.

Here is the caller graph for this function:

◆ special()

static bool special ( int ch )

inlinestatic

Thinking in non-internationalized US-ASCII (per the DNS spec), is this character special ("in need of quoting")?

Note: This is a helper function for rip_ns_name_ntop()

Parameters

ch	Character to check.

Returns: Returns true if character needs quoting, otherwise returns false.

Here is the caller graph for this function:
