GstIdStr
A GstIdStr is string type optimized for short strings and used for structure names, structure field names and in other places.
Strings up to 16 bytes (including NUL terminator) are stored inline, other strings are stored on the heap.
GstIdStr s = GST_ID_STR_INIT;
gst_id_str_set (&s, "Hello, World!");
g_print ("%s\n", gst_id_str_as_str (&s));
gst_id_str_clear (&s);
GstIdStr
String type optimized for short strings.
Strings are usually stack- or inline-allocated, and for short strings smaller than 16 bytes (including NUL terminator) no heap allocations are performed.
