4.14.1.2 Description of Interface Functions
RSDLLibfind()
The function provides a handle for access to the device with the name
udName
.
The function must be called prior to all other functions of the interface.
As return value, the function provides a handle that must be indicated in all functions
for access to the device. If the device with the name
udName
is not found, the han-
dle has a negative value.
RSDLLibwrt
This function sends data to the device with the handle
ud
.
This function allows setting and query commands to be sent to the measuring instru-
ments. Whether the data is interpreted as a complete command can be set using the
function
RSDLLibeot()
.
RSDLLilwrt
This function sends
Cnt
bytes to a device with the handle
ud
.
VB format:
Function RSDLLibfind (ByVal udName$, ibsta%,
iberr%, ibcntl&) As Integer
C format:
short WINAPI RSDLLibfind( char far *udName,
short far *ibsta, short far *iberr, unsigned
long far *ibcntl)
C format (UNIX):
short RSDLLibfind( char *udName, short
*ibsta, short *iberr, unsigned long *ibcntl)
Parameters:
udName
IP address of device
Example:
ud = RSDLLibfind ("89.10.38.97", ibsta,
iberr, ibcntl)
VB format:
Function RSDLLibwrt (ByVal ud%, ByVal Wrt$,
ibsta%, iberr%, ibcntl&) As Integer
C format:
short WINAPI RSDLLibwrt( short ud, char far
*Wrt, short far *ibsta, short far *iberr,
unsigned long far *ibcntl )
C format (UNIX):
short RSDLLibwrt( short ud, char *Wrt, short
*ibsta, short *iberr, unsigned long *ibcntl
)
Parameters:
ud
Device handle
Wrt
String sent to the device.
Example:
RSDLLibwrt(ud, "SENS:FREQ:STAR?", ibsta,
iberr, ibcntl)
VB format:
Function RSDLLilwrt (ByVal ud%, ByVal Wrt$,
ByVal Cnt&, ibsta%, iberr%, ibcntl&) As
Integer
