Functions for manipulating Universal Resource Identifiers (URIs) as defined by RFC 3986. It is highly recommended that you have read and understand RFC 3986 for understanding this API.
#define G_URI_RESERVED_CHARS_ALLOWED_IN_PATH G_URI_RESERVED_CHARS_ALLOWED_IN_PATH_ELEMENT "/"
Allowed characters in a path. Includes "!$&'()*+,;=:@/".
#define G_URI_RESERVED_CHARS_ALLOWED_IN_PATH_ELEMENT G_URI_RESERVED_CHARS_SUBCOMPONENT_DELIMITERS ":@"
Allowed characters in path elements. Includes "!$&'()*+,;=:@".
#define G_URI_RESERVED_CHARS_ALLOWED_IN_USERINFO G_URI_RESERVED_CHARS_SUBCOMPONENT_DELIMITERS ":"
Allowed characters in userinfo as defined in RFC 3986. Includes "!$&'()*+,;=:".
#define G_URI_RESERVED_CHARS_GENERIC_DELIMITERS ":/?#[]@"
Generic delimiters characters as defined in RFC 3986. Includes ":/?#[]@".
#define G_URI_RESERVED_CHARS_SUBCOMPONENT_DELIMITERS "!$&'()*+,;="
Subcomponent delimiter characters as defined in RFC 3986. Includes "!$&'()*+,;=".
char * g_uri_parse_scheme (const char *uri);
Gets the scheme portion of a URI string. RFC 3986 decodes the scheme as:
URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
Common schemes include "file", "http", "svn+ssh", etc.
|
a valid URI. |
Returns : |
The "Scheme" component of the URI, or NULL on error.
The returned string should be freed when no longer needed.

Since 2.16
char * g_uri_escape_string (const char *unescaped, const char *reserved_chars_allowed, gboolean allow_utf8);
Escapes a string for use in a URI.
Normally all characters that are not "unreserved" (i.e. ASCII alphanumerical
characters plus dash, dot, underscore and tilde) are escaped.
But if you specify characters in reserved_chars_allowed
they are not
escaped. This is useful for the "reserved" characters in the URI
specification, since those are allowed unescaped in some portions of
a URI.
|
the unescaped input string. |
|
a string of reserved characters that are allowed to be used. |
|
TRUE if the result can include UTF-8 characters.
|
Returns : |
an escaped version of unescaped . The returned string should be
freed when no longer needed.
|
Since 2.16
char * g_uri_unescape_string (const char *escaped_string, const char *illegal_characters);
Unescapes a whole escaped string.
If any of the characters in illegal_characters
or the character zero appears
as an escaped character in escaped_string
then that is an error and NULL
will be returned. This is useful it you want to avoid for instance having a
slash being expanded in an escaped path element, which might confuse pathname
handling.
|
an escaped string to be unescaped. |
|
an optional string of illegal characters not to be allowed. |
Returns : |
an unescaped version of escaped_string . The returned string
should be freed when no longer needed.
|
Since 2.16
char * g_uri_unescape_segment (const char *escaped_string, const char *escaped_string_end, const char *illegal_characters);
Unescapes a segment of an escaped string.
If any of the characters in illegal_characters
or the character zero appears
as an escaped character in escaped_string
then that is an error and NULL
will be returned. This is useful it you want to avoid for instance having a
slash being expanded in an escaped path element, which might confuse pathname
handling.
