Function Documentation

gate_uri_init()

GATE_CORE_API gate_result_t gate_uri_init

(

gate_uri_t *

uri

)

Initializes an empty URI object.

Parameters

[out]

uri

Pointer to URI object to be initialized

Returns

GATE_RESULT_* code

gate_uri_copy()

GATE_CORE_API gate_result_t gate_uri_copy	(	gate_uri_t *	target,
		gate_uri_t const *	src )

Initializes an URI object by copying data from another URI object.

Parameters

[out]	target	Pointer to target URI object to be initialized
[in]	src	Pointer to source URI object to copy content from

Returns

GATE_RESULT_* code

gate_uri_destroy()

GATE_CORE_API gate_result_t gate_uri_destroy

(

gate_uri_t *

uri

)

Destroys the URI object by releasing all its contained strings.

Parameters

[in]

uri

Pointer to target URI object to be destroyed

Returns

GATE_RESULT_* code

gate_uri_parse()

GATE_CORE_API gate_result_t gate_uri_parse	(	gate_uri_t *	uri,
		gate_string_t const *	text )

Initializes an URI object by parsing a text string.

Parameters

[out]	uri	Pointer to target URI object to be initialized
[in]	text	Pointer to source string to be parsed

Returns

GATE_RESULT_* code

gate_uri_to_string()

GATE_CORE_API gate_result_t gate_uri_to_string	(	gate_uri_t const *	uri,

Creates a string from the contents of the given URI object.

Parameters

[in]	uri	Pointer to source URI object
[out]	text	Pointer to target string to be initialized with URI's content
[in]	absolute_path_only	If TRUE, only the path part is exported - schema, user and host is skipped

Returns

GATE_RESULT_* code

gate_uri_escape()

GATE_CORE_API gate_result_t gate_uri_escape	(	gate_string_t const *	src,

[out]	dest	Pointer to target string to be initialized with plain content

Returns

GATE_RESULT_* code

gate_uri_parse_user_info()

GATE_CORE_API gate_result_t gate_uri_parse_user_info	(	gate_string_t const *	src,
		gate_string_t *	username,
