Checks if a content type can be executable. Note that for instance things like text files can be executables (i.e. scripts and batch files).
Gets a list of strings containing all the registered content types known to the system. The list and its data should be freed using g_list_free_full (list, g_free).
Compares two content types for equality.
Tries to find a content type based on the mime type name.
Gets the human readable description of the content type.
Gets the generic icon name for a content type.
Gets the icon for a content type.
Gets the mime type for the content type, if one is registered.
Gets the symbolic icon for a content type.
Tries to guess the type of the tree with root @root, by looking at the files it contains. The result is an array of content types, with the best guess coming first.
Determines if @type is a subset of @supertype.
Checks if the content type is the generic "unknown" type. On UNIX this is the "application/octet-stream" mimetype, while on win32 it is "*".
Guesses the content type based on example data. If the function is uncertain, @result_uncertain will be set to %TRUE. Either @filename or @data may be %NULL, in which case the guess will be based solely on the other argument.
