return value checking for GTK APIs

[brahmaiah vallabhaneni <vbrahmaiah yahoo com>]

Hi All,
 I am new to Linux GUI programming and started going
 through the tutorial.

 But I have observed one strange coding style (to me).
 Usually, when we call a function say malloc, we 
 always validate the return value before it's use.

 But in GTK samples, they do n't check the return
 value of APIs. Any specific reason ?

 Is it always guranteed that these APIs succeed ?

 Pls tell me if I am missing some thing....

Thanks and Regards,

V.Brahmaiah
