Function Documentation

fr_table_value_by_longest_prefix()

return fr_table_value_by_longest_prefix	(	NULL	,
		schemes	,
		fr_sbuff_start &	sbuff,
		fr_sbuff_used &	sbuff,
		def
	)

Here is the caller graph for this function:

fr_uri_escape()

int fr_uri_escape	(	fr_value_box_t *	uri_vb,
		void *	uctx
	)

Escapes an individual value box that's part of a URI, advancing the pointer to uri_parts.

Note

This function has a signature compatible with fr_uri_escape_func_t.

This function may modify the type of boxes, as all boxes in the list are cast to strings before parsing.

Parameters

[in,out]	uri_vb	to escape
[in]	uctx	A fr_uri_escape_ctx_t containing the initial fr_uri_part_t and the uctx to pass to the escaping function.

Returns

• 0 on success.
• -1 on failure.

fr_uri_escape_list()

int fr_uri_escape_list	(	fr_value_box_list_t *	uri,
		fr_uri_part_t const *	uri_parts,
		void *	uctx
	)

Parse a list of value boxes representing a URI.

Reads a URI from a list of value boxes and parses it according to the definition in uri_parts. Tainted values, where allowed, are escaped using the function specified for the uri part.

Note

This function may modify the type of boxes, as all boxes in the list are cast to strings before parsing.

Parameters

uri	to parse. A list of string type value boxes containing fragments of a URI.
uri_parts	definition of URI structure. Should point to the start of the array of uri parts.
uctx	to pass to escaping function

Returns

• 0 on success
• -1 on failure

fr_uri_has_scheme()

int fr_uri_has_scheme	(	fr_value_box_list_t *	uri,
		fr_table_num_sorted_t const *	schemes,
		size_t	schemes_len,
		int	def
	)

Searches for a matching scheme in the table of schemes, using a list of value boxes representing the URI.

Note

Unlikel

Parameters

uri	to parse. A list of string type value boxes containing fragments of a URI.
schemes	Table of schemes to search.
schemes_len	Number of schemes in the table.
def	Default scheme to use if none is found.

Returns

The matching scheme, or def if none is found.
