[gst-devel] how to customize gstmesage in application?

[Edward Hervey]

Go back to first courses of C programming,

  look at the structure, look at how you're accessing the 3 first
elements of the structure, and how you're accessing the 2 last.
  Now try to think why the compiler is complaining only about the first
3 ones.
