Determines whether the file pointer is positioned at the end of a file.
FEOF(nFileHandle) |
Parameters
- nFileHandle
- Specifies the file handle number of the file to check for the end-of-file condition. FEOF(В ) always returns true (.T.) if you specify a file handle number of a communication port opened with FOPEN(В ).
Return Value
Logical
Remarks
This low-level file function returns true (.T.) if the file pointer is positioned at the end of a file opened with a low-level file function. FEOF(В ) returns false (.F.) if the file pointer isn't at the end of the file.
Example
| В |  Copy Code |
|---|---|
*** Open the file test.txt ***
gnFileHandle = FOPEN('test.txt')
*** Move the file pointer to BOF ***
gnPosition = FSEEK(gnFileHandle, 0)
*** If file pointer is at BOF and EOF, the file is empty ***
*** Otherwise the file must have something in it ***
IF FEOF(gnFileHandle)
WAIT WINDOW 'This file is empty!' NOWAIT
ELSE
WAIT WINDOW 'This file has something in it!' NOWAIT
ENDIF
= FCLOSE(gnFileHandle) | |
