Description of Interface Functions
RSDLLibfind()
The function provides a handle for access to the device with the name udName.
VB format: Function RSDLLibfind (ByVal udName$, ibsta%, iberr%, ibcntl&)
As Integer
C format: short WINAPI RSDLLibfind( char far *udName, short far *ibsta,
short far *iberr, unsigned long far *ibcntl)
C format (UNIX): short RSDLLibfind( char *udName, short *ibsta, short *iberr,
unsigned long *ibcntl)
Parameters: udName IP address of device
Example: ud = RSDLLibfind ("89.10.38.97", ibsta, iberr, ibcntl)
The function must be called prior to all other functions of the interface.
As return value, the function provides a handle that must be indicated in all functions for access to the
device. If the device with the name udName is not found, the handle has a negative value.
RSDLLibwrt
This function sends data to the device with the handle ud.
VB format: Function RSDLLibwrt (ByVal ud%, ByVal Wrt$, 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)
This function allows setting and query commands to be sent to the measuring instruments. 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 RSDLLilwrt (ByVal ud%, ByVal Wrt$, ByVal Cnt&,
ibsta%, iberr%, ibcntl&) As Integer
C format: short WINAPI RSDLLilwrt( short ud, char far *Wrt,
unsigned long Cnt, short far *ibsta, short far *iberr,
unsigned long far *ibcntl)
C format (UNIX): short RSDLLilwrt( short ud, char *Wrt, unsigned long Cnt,
short *ibsta, short *iberr, unsigned long *ibcntl)
Parameters: ud Device handle
Wrt String sent to the GPIB parser.
Cnt Number of bytes sent to the device.
Example: RSDLLilwrt (ud, '......', 100, ibsta, iberr, ibcntl)
Like RSDLLibwrt() this function sends data to a device. The only difference is that binary data can be
sent as well. The length of the data is not determined by a zero-terminated string, but by the indication of
Cnt bytes. If the data is to be terminated with EOS (0Ah), the EOS byte must be appended to the string.
