Function Documentation

a_Misc_content_type_check()

int a_Misc_content_type_check	(	const char *	EntryType,
		const char *	DetectedType
	)

Check the server-supplied 'Content-Type' against our detected type.

(some servers seem to default to "text/plain").

Returns

• 0, if they match
• -1, if a mismatch is detected

There are many MIME types Dillo doesn't know, they're handled as "application/octet-stream" (as the SPEC says).

A mismatch happens when receiving a binary stream as "text/plain" or "text/html", or an image that's not an image of its kind.

Note: this is a basic security procedure.

a_Misc_content_type_cmp()

int a_Misc_content_type_cmp	(	const char *	ct1,
		const char *	ct2
	)

Compare two Content-Type strings.

Return 0 if they are equivalent, and 1 otherwise.

Load a local file into a dStr.

Return value: dStr on success, NULL on error. TODO: a filesize threshold may be implemented.

a_Misc_get_content_type_from_data()

int a_Misc_get_content_type_from_data	(	void *	Data,
		size_t	Size,
		const char **	PT
	)

Detects 'Content-Type' from a data stream sample.

It uses the magic(5) logic from file(1). Currently, it only checks the few mime types that Dillo supports.

'Data' is a pointer to the first bytes of the raw data.

Return value: (0 on success, 1 on doubt, 2 on lack of data).
