Parameters

tag

Type: const gchar*

Exiv2 tag name.

The data is owned by the caller of the method.
The value is a NUL terminated UTF-8 string.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will be left initialized to NULL by the method if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: An array of utf8

The multiple string values of the tag. Returns NULL if parameters are NULL or tag does not begin with recognised type of metadata (“Exif.”, “Xmp.” or “Iptc.”). For a well formed tag, returns array[0] = NULL if tag is undefined or is not set in the current metadata.

The array is NULL-terminated.
The caller of the method takes ownership of the returned data, and is responsible for freeing it.
The return value can be NULL.
Each element is a NUL terminated UTF-8 string.
