Reading Data From The Comm Port

Function Description:

Set the scanner to the working mode, and reset the communication control.

Function call:

BOOL ReadFile (HANDLE hFile, LPCVOID lpBuffer, DWORD nNumberOfBytesToRead,
LPDWORD lpNumberOfBytesRead, LPOVERLAPPED lpOverlapped);

Parameters(Input):

hFile:

HANDLE

: Handle to the com port to read from.

nNumberOfBytesToRead: DWORD

The

exact number of bytes you wish to

read from the data stream. The function will pause until this number or a timeout is reached.
lpOverlapped:

LPOVERLAPPED

: Not Supported, set to Null.

Parameters(Output):

lpBuffer:

LPCVOID

: Pointer to buffer containing data to write.

lpNumberOfBytesRead:

LPDWORD

pointer to a DWORD that will contain the

number of bytes read. A value of 0 will indicate there was no data in the stream and timeout
occured.

12.3.5.

Get error code

Function Description:

Read or Write functions will return Boolean false if there is a failure. The GetLastError() function will
then return the reason for the failure.

Function call:

DWORD GetLastError();

Return code:

Returns the error code most recently set. This must be called immediately after the failing function
to be relevant. See line 224 of the sample program.
