Bool gf_url_is_local

(

const char *

url

gf_url_get_absolute_path()

char* gf_url_get_absolute_path	(	const char *	pathName,
		const char *	parentPath
	)

Gets the absolute file path from a relative path and its parent absolute one. This can only be used with file paths.

Parameters

pathName	the relative path name of a file
parentPath	the absolute parent path name

Returns

absolute path name of the file, or NULL if bad paths are provided.

Note

the returned string must be freed by user

gf_url_concatenate()

char* gf_url_concatenate	(	const char *	parentName,
		const char *	pathName
	)

Concatenates a relative URL with its parent URL

Parameters

parentName	URL of the parent service
pathName	URL of the service

Returns

absolute path name of the service, or NULL if bad paths are provided or if the service path is already an absolute one.

Note

the returned string must be freed by user

gf_url_concatenate_parent()

char* gf_url_concatenate_parent	(	const char *	parentName,
		const char *	pathName
	)

Same as gf_url_concatenate but if both paths are relative, resolved url is relative to parent path.

Parameters

parentName	URL of the parent service
pathName	URL of the service

Returns

absolute path name of the service, or NULL if bad paths are provided or if the service path is already an absolute one.

gf_url_percent_encode()

char* gf_url_percent_encode

(

const char *

path

)

Encodes URL by replacing special characters with their % encodings.

Parameters

path	URL of the service

Returns

encoded path name , or NULL if bad paths are provided.

Decodes URL by % encodings with the special characters they correspond to

Parameters

path	encoded URL of the service

Returns

url

)

Converts a local URL to a file system value. Removes all white spaces and similar

Parameters

url	url to convert

Here is the caller graph for this function:

gf_url_is_relative()

Bool gf_url_is_relative

(

const char *

url

)

Checks if given URL is absolute or relative

Parameters

url	url to check

Returns

GF_TRUE if URL is relative

Here is the caller graph for this function:

gf_url_colon_suffix()

char* gf_url_colon_suffix	(	const char *	URL,
		char	assign_sep
	)

Returns a pointer to the first colon at the end of a filename or URL, if any.

If assign_sep is specified, for example '=', the function will make sure that the colon is after the file extension if found and that '=' is not present between colon and file ext. This is used to parse 'a:b.mp4:c' (expected result ':c...' and not ':b...') vs 'a:b=c.mp4' ' (expected result ':b')

Parameters

URL	path or URL to inspect
assign_sep	value of assignment operand character. If 0, only checks for colon, otherwise chec that no assign sep or colon is present before file extension, if present

Returns

position of first colon, or NULL
