FT_FLOPTST()
Test diskette drive status
------------------------------------------------------------------------------
Syntax
FT_FLOPTST( <nDrive> ) -> nStatus
Arguments
<nDrive> is the diskette drive number, 0 = A:, 1 = B:
Returns
-1 - Wrong Parameters
0 - Drive Loaded and ready to read or write
1 - Drive Door Open or Diskette inserted upside down
2 - Diskette is unformatted
3 - Write protected
4 - Undetermined
Description
FT_FLOPTST() is designed as a full replacement for ISDRIVE(). Where
ISDRIVE() returns just .T. or .F. depending if the diskette drive is
ready or not, FT_FLOPTST() returns a numeric code designating the
diskette drive's status.
FT_FLOPTST() is particularly useful in backup and restore programs
that need to test the floppy drive before writing/reading from a
floppy disk.
Examples
iStatus := FT_FLOPTST( 1 )
DO CASE
CASE iStatus == 1
Qout( "The door to drive A is open." )
CASE iStatus == 2
Qout( "The diskette in drive A is not formatted." )
CASE iStatus == 3
Qout( "The diskette in drive A is write-protected." )
CASE iStatus == 4
Qout( "Something is wrong with drive A, but I don't know what." )
ENDCASE
