KEEP

#define KEEP	(		component,
			also
	)

Value:

        do { \
        if (uc.url_component_end_##component == uc.url && \
            ub.url_component_end_##component > keep) { \
            keep = ub.url_component_end_##component; \
            also \
        } \
    } while (0)

COPY

#define COPY	(		start,
			end
	)

Value:

        do { \
        size_t len = end - start; \
        if (len > out_end - out) { \
            ret = AVERROR(ENOMEM);  \
            goto error; \
        } \
        memmove(out, start, len); \
        out += len; \
    } while (0)

ff_url_decompose()

int ff_url_decompose	(	URLComponents *	uc,
		const char *	url,
		const char *	end
	)

Parse an URL to find the components.

Each component runs until the start of the next component, possibly including a mandatory delimiter.

Parameters

uc	structure to fill with pointers to the components.
url	URL to parse.
end	end of the URL, or NULL to parse to the end of string.

Returns

>= 0 for success or an AVERROR code, especially if the URL is malformed.

ff_make_absolute_url2()

int ff_make_absolute_url2	(	char *	buf,
		int	size,
		const char *	base,
		const char *	rel,
		int	handle_dos_paths
	)

Convert a relative url into an absolute url, given a base url.

Parameters

buf	the buffer where output absolute url is written
size	the size of buf
base	the base url, may be equal to buf.
rel	the new url, which is interpreted relative to base
handle_dos_paths	handle DOS paths for file or unspecified protocol

ff_make_absolute_url()

int ff_make_absolute_url	(	char *	buf,
		int	size,
		const char *	base,
		const char *	rel
	)

Convert a relative url into an absolute url, given a base url.

Same as ff_make_absolute_url2 with handle_dos_paths being equal to HAVE_DOS_PATHS config variable.
