Return Value
Each of these functions returns the current file position within the file. -1 indicates an error.
Parameters
handle
A handle to the open file
Remarks
The _tell function returns the internal character counter for handle which may not represent the number of bytes used by the file when text translation mode has been chosen. Any padding added, to complete records, is not counted in the return value. When the file remains in the same mode, the result returned will reposition to the correct location when used with the _lseek function.
