FEOF( ) Function
Determines whether the file pointer is positioned at the end of a file.
FEOF(nFileHandle)
Return Value
Logical
Parameters
- nFileHandle
Specifies the file handle number of the file to check for the end-of-file condition. FEOF( ) always returns true (.T.) if you specify a file handle number of a communication port opened with FOPEN( ).
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( ) returns false (.F.) if the file pointer isn't at the end of the file.
Example
** 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)
