Structure.getDateTime
bool getDateTime(string fieldname, out gst.date_time.DateTime value)Sets the datetime pointed to by value corresponding to the datetime of the given field. Caller is responsible for making sure the field exists and has the correct type.
On success value will point to a reference of the datetime which should be unreffed with [gst.date_time.DateTime.unref] when no longer needed (note: this is inconsistent with e.g. [gst.structure.Structure.getString] which doesn't return a copy of the string).
Parameters
fieldname | the name of a field |
value | a pointer to a #GstDateTime to set |
Returns
true if the value could be set correctly. If there was no field
