FileClose

SIGNED_INTEGER FileClose (INTEGER handle) 

Closes a file opened previously by FileOpen. You MUST close a file that was 
opened, you won’t be able to open it again, or eventually the control system may hang 
or reboot. A reboot clears all open files. Files must be opened and closed during a 
single thread of operation. Refer to “StartFileOperations()” on 

.

HANDLE specifies the file handle of the previously opened file (from FileOpen).

Returns 0 if successful. Otherwise, file error code is returned.

(Refer to  "File Functions Overview"on page 

)

StartFileOperations();

PRINT(“Error Opening File MyFile\n”);

return;

}

IF ( nFileHandle > 0 ) 

{

IF ( FileClose ( nFileHandle ) <> 0 ) 

PRINT ( “Error closing file\n” );
