Detailed Description

MIME type sniffer interface.

Definition in file mimesniff.h.

Function Documentation

mimesniff_compute_effective_type()

nserror mimesniff_compute_effective_type	(	const char *	content_type_header,
		const uint8_t *	data,
		size_t	len,
		bool	sniff_allowed,
		bool	image_only,
		lwc_string **	effective_type
	)

Compute the effective MIME type for an object.

The implementation uses the sniffing algorithm described in http://mimesniff.spec.whatwg.org/

Parameters

content_type_header	Source content type header
data	First data chunk, or NULL
len	Length of data, in bytes
sniff_allowed	Whether MIME type sniffing is allowed
image_only	Sniff image types only
effective_type	Location to receive computed type

Returns

NSERROR_OK on success, NSERROR_NEED_DATA iff data is NULL and data is needed NSERROR_NOT_FOUND if sniffing is prohibited and no Content-Type header was found
