Returns

A pointer to a newly allocated cinfo structure if the find succeeds, or NULL if the find fails.

The cinfo structure that is allocated and returned contains pointers to the content-type, content-encoding, and content-language, if found. Each structure points to static data in the types database, or NULL if not found. Do not free these pointers. You should free the cinfo structure after using it.
