/***
*int fgetpos(stream,pos) - Get file position (internal format)
*
*Purpose:
* Fgetpos gets the current file position for the file identified by
* [stream]. The file position is returned in the object pointed to
* by [pos] and is in internal format; that is, the user is not supposed
* to interpret the value but simply use it in the fsetpos call. Our
* implementation simply uses fseek/ftell.
*
*Entry:
* FILE *stream = pointer to a file stream value
* fpos_t *pos = pointer to a file position value
*
*Exit:
* Successful fgetpos call returns 0.
* Unsuccessful fgetpos call returns non-zero (!0) value and sets
* ERRNO (this is done by ftell and passed back by fgetpos).
*
*Exceptions:
* None.
