scnGets

Description

Initiates a scan and moves the scanner buffer’s contents to a

programmer-defined application buffer as a null-terminated

string. If the scanner buffer is empty, this function activates the

scanner to let the operator scan a bar code. This function

works with each scanner.

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 scnGetScannedData to retrieve the scanner buffer’s

contents without activating the scanner when the buffer is

empty.

Syntax

char far * far scnGets(char far *lpszData);

Parameters

lpszData

A pointer to a programmer-defined application

buffer where the function copies the scanner

buffer’s contents. This buffer must be one byte

longer than the largest string that you may scan.

Return Values

A pointer to the

buffer parameter

Successful.

NULL pointer

An error occurred.
