_FEOF( ) API Library Routine

Visual Studio .NET 2003
int _FEOF(FCHAN chan)
FCHAN chan;               /* File channel of file. */


_FEOF( ) returns True (an integer other than 0) if the file pointer in the specified file is currently at the end of the file; or False (0) if not.

For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.


The following example creates a file and sets its length to 8192 bytes. Then it moves the file pointer to the beginning of the file and calls _FEOF( ), which returns 0 (False). Next, it moves the file pointer to the end of the file and again calls _FEOF( ), which this time returns 1 (True).

Visual FoxPro Code


C Code

#include <pro_ext.h>

void putLong(long n)
   Value val;

   val.ev_type = 'I';
   val.ev_long = n;
   val.ev_width = 10;


FAR Example(ParamBlk FAR *parm)
   FCHAN fchan =  FCreate("temp.txt", FC NORMAL);
    FCHSize(fchan, 8196);

    FSeek(fchan, 0, FS FROMBOF);
    PutStr("\n FSeek(fchan, 0, FS FROMBOF)");
    PutStr("\n FEOF(fchan) ="); putLong(_FEOF(fchan));

   _FSeek(fchan, 0, FS_FROMEOF);
   _PutStr("\n_FSeek(fchan, 0, FS_FROMEOF)");
   _PutStr("\n_FEOF(fchan) ="); putLong(_FEOF(fchan));

FoxInfo myFoxInfo[] = {
   {"FEOF", (FPFI) Example, CALLONLOAD, ""},
FoxTable _FoxTable = {
   (FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
