const char* gnome_vfs_mime_type_from_name (const char *filename);
gnome_vfs_mime_type_from_name is deprecated and should not be used in newly-written code. This function is deprecated, use gnome_vfs_get_mime_type_for_name() instead.
Determine the mime type for filename.
Returns:
filename : | a filename (the file does not necessarily exist). |
Returns : | the mime-type for this filename. Will return GNOME_VFS_MIME_TYPE_UNKNOWN if mime-type could not be found. |
const char* gnome_vfs_mime_type_from_name_or_default (const char *filename, const char *defaultv);
This routine tries to determine the mime-type of the filename only by looking at the filename from the GNOME database of mime-types.
filename : | a filename (the file does not necessarily exist). |
defaultv : | a default value to be returned if no match is found. |
Returns : | the mime-type of the filename. If no value could be determined, it will return defaultv. |
const char* gnome_vfs_get_mime_type_common (GnomeVFSURI *uri);
Tries to guess the mime type of the file represented by uri. Favors using the file data to the uri extension. Handles uri of a non-existent file by falling back on returning a type based on the extension. If cant find the mime-type based on the extension also then returns 'application/octet-stream'.
FIXME: This function will not necessarily return the same mime type as doing a get file info on the text uri.
uri : | a real file or a non-existent uri. |
Returns : | the mime-type for uri. |
const char* gnome_vfs_get_mime_type_from_uri (GnomeVFSURI *uri);
Tries to guess the mime type of the file uri by checking the file name extension. Works on non-existent files.
uri : | a file uri. |
Returns : | the mime-type for file at uri. |
const char* gnome_vfs_get_mime_type_from_file_data (GnomeVFSURI *uri);
gnome_vfs_get_mime_type_from_file_data is deprecated and should not be used in newly-written code.
Tries to guess the mime type of the file uri by checking the file data using the magic patterns. Does not handle text files properly.
Returns:
uri : | a file uri. |
Returns : | the mime-type for this filename. |
const char* gnome_vfs_get_file_mime_type_fast (const char *path, const struct stat *optional_stat_info);
Tries to guess the mime type of the file represented by path. It uses extention/name detection first, and if that fails it falls back to mime-magic based lookup. This is faster than always doing mime-magic but doesn't always produce the right answer, so for important decisions you should use gnome_vfs_get_file_mime_type().
path : | path of the file whose mime type is to be found out. |
optional_stat_info : | optional stat buffer. |
Returns : | the mime-type for file at path. |
const char* gnome_vfs_get_file_mime_type (const char *path, const struct stat *optional_stat_info, gboolean suffix_only);
Tries to guess the mime type of the file represented by path. If suffix_only is false, uses the mime-magic based lookup first. Handles path of a non-existent file by falling back on returning a type based on the extension.
If you need a faster, less accurate version, use gnome_vfs_get_file_mime_type_fast().
path : | path of a file whose mime type is to be found out. |
optional_stat_info : | optional stat buffer. |
suffix_only : | whether or not to do a magic-based lookup. |
Returns : | the mime-type for file at path. |
gboolean gnome_vfs_mime_type_is_supertype (const char *mime_type);
mime_type : | a const char * identifying a mime type. |
Returns : | Whether mime_type is of the form "foo/*". |
char* gnome_vfs_get_supertype_from_mime_type (const char *mime_type);
mime_type : | mime type to get the supertype for. |
Returns : | The supertype for mime_type, allocating new memory.
The supertype of an application is computed by removing its
suffix, and replacing it with "*". Thus, "foo/bar" will be
converted to "foo/*".
NoteIf this function is called on a supertype, it will return a copy of the supertype. |
void gnome_vfs_mime_info_cache_reload (const char *dir);
Reload the mime information for the dir.
dir : | directory path which needs reloading. |
void gnome_vfs_mime_shutdown (void);
gnome_vfs_mime_shutdown is deprecated and should not be used in newly-written code. This function doesn't have to be called as the operating system automatically cleans up resources when exiting.
Unload the MIME database from memory.
