Caller is responsible for unrefing the result.
|
GOData |
Returns : |
the fmt preferred by the the data |
go_data_date_conv ()
GODateConventions const * go_data_date_conv (GOData const *dat

|
GOData |
Returns : |
the date conventions used by the data, or NULL if not determined. |
go_data_serialize ()

NOTE : This is the _source_ not the content. (I.e., this refers to the expression, not its current value.)
|
GOData |
|
a gpointer describing the context. |
Returns : |
a string representation of the data source that the caller is responsible for freeing |
go_data_unserialize ()
gboolean go_data_unserialize (GOData *dat
,char const *str
,gpointer user
);
De-serializes the source information returned from go_data_serialize.
