Declaration [src]

gboolean
gexiv2_metadata_set_tag_string (
  GExiv2Metadata* self,
  const gchar* tag,
  const gchar* value,
  GError** error
)

Description [src]

The Exiv2 Tag Reference can be found at http://exiv2.org/metadata.html

If a tag supports multiple values, then value is added to any existing values. For single value tags, value replaces the value.

In case of error, a GLib warning will be logged. Use instead gexiv2_metadata_try_set_tag_string() if you want to avoid this and control if and how the error is outputted.

Available since: 0.16.0

Exiv2 tag name.
