Hi people.
I am Antonello Stella.
I have bought a Tasking's compiler C for 8051 family and I have a problem.
I don't understand the meaning of next statement:

Typedef _idat unsigned char FILE
#define stdin (FILE *)0.

Principally, the part that isn't clear is: (FILE *)0.
Can anyone help me to understand this statement.
Thanks.
Kind Regard.
