Description
Retrieves the scanner buffer’s contents as a null-terminated
string, placing them in a programmer-defined application buffer.
If the scanner buffer is empty, this function does not activate
the trigger to start a scan. This function works with both
scanners.
If there is any chance the scanned bar code
contains a binary zero, do not use this
function. Instead, use scnGetch and
scnScannerHit in a loop until the scan is
complete.
Use scnGets to retrieve the scanner buffer’s contents and
activate the scanner when the buffer is empty.
Syntax
short far scnGetScannedData(char far *lpszData);
Parameters
lpszData A pointer to a programmer-defined application buffer
where the function places the scanner buffer’s
contents. This buffer must be one byte longer than the
largest string that you may scan.
Return Values
0 No data available.
-1 Checksum, time-out, or communications error.
-2 Decoding fault. The scanner scanned the bar code,
but the printer could not decode it.
-9 Scanner is disabled.
