Additional Output Functions
Driver488 provides additional
Output functions that are short-form versions of the OutputX function.
The following Output functions are already defined in your header file.
Output
Syntax LONG WINAPI Output(DevHandleT devHandle,LPBYTE data);
Remarks Output is equivalent to the following call to OutputX :
OutputX(devHandle,data,strlen(data),1,1,0L,0,0L);
The Output function passes the device handle and data buffer to the OutputX function. It determines the
size of the data buffer that you provided, and passes that value as the count parameter. It specifies that the
forceAddr flag is set TRUE , which causes Driver488 to address the device if an external device is
specified. The default terminators are chosen by specifying a 0 pointer as the terminator parameter.
Synchronous transmission is specified by sending 0 for the async parameter, and the completion status
value is ignored by sending a 0 for the compStat pointer.
OutputN
Syntax LONG WINAPI OutputN(DevHandleT devHandle,LPBYTE data,DWORD
count);
Remarks OutputN is equivalent to the following call to OutputX :
OutputX(devHandle,data,count,0,1,0L,0,0L);
The OutputN function passes the device handle and a pointer to the data buffer to the OutputX function.
It specifies that the forceAddr flag is set TRUE , which causes Driver488 to address the device if an
external device is specified. The default terminators are chosen by specifying a 0 pointer as the
terminator parameter. Synchronous transmission is specified by sending 0 for the async parameter, and
the completion status value is ignored by sending a 0 for the compStat pointer.
OutputMore
Syntax LONG WINAPI OutputMore(DevHandleT devHandle, LPBYTE data);
Remarks OutputMore is equivalent to the following call to OutputX :
OutputX(devHandle,data,strlen(data),1,0,0L,0,0L);
The OutputMore function passes the device handle and data buffer to the OutputX function. It
determines the size of the data buffer that you provided, and passes that value as the count parameter. It
specifies that the forceAddr flag is set FALSE , so Driver488 does not re-address the device if it is the
same device as that previously used. The default terminators are chosen by specifying a 0 pointer as the
terminator parameter. Synchronous transmission is specified by sending 0 for the async parameter, and
the completion status value is ignored by sending a 0 pointer for the compStat pointer.
OutputNMore
Syntax LONG WINAPI OutputNMore (DevHandleT devHandle, LPBYTE data,
DWORD count);
Remarks OutputNMore is equivalent to the following call to OutputX :
OutputX(devHandle,data,0,0,0L,0,0L);
The OutputNMore function passes the device handle and a pointer to the data buffer to the OutputX
function. It specifies that the forceAddr flag is set FALSE , so Driver488 does not re-address the device if
it is the same device as that previously used. The default terminators are chosen by specifying a 0 pointer
as the terminator parameter. Synchronous transmission is specified by sending 0 for the async
parameter, and the completion status value is ignored by sending a 0 pointer for the compStat pointer.
