Adding a Device for C I/O

Hi,

I am trying to implement file read/write operation uisng the sample program

as shown in page 120 of C/C++ Compiler user guide but not getting proper result.

http://focus.ti.com.cn/cn/lit/ug/slau132b/slau132b.pdf

I have few doubts as below..

1.file open described in page 117 describes that it returns #-1 if successful,

what is "#"?

2.I think in open file(),the buffer size and address should be defined,

where can I find the details about that

3.The fopen go into the open routine and works properly, but

 fprintf  doesnot go to the write function.

if anybody has some hint please guide me...

Thankyou and Regards.
