I'm now taking a look at the PocketC powerful tool, but there is an fileopen function, that generates a integer called filehandle, that is used for most of the File I/O operations of PocketC, than I want to know how to discover the int filehandle from the function?

Here is my example function that I'm using at my program:

fileopen("\test.txt", 0, 0x00000000);

Description of int filehandle: Integer used for file operations, used as a pointer to the fileopen instruction.
