1145.1084.12 8.14 E-3
Parameter:
ud
Device handle
Wrt
String sent to the device.
Example: RSDLLibwrt(ud, "SENS:FREQ:STAR?", ibsta, iberr, ibcntl)
This function allows to send setting and query commands 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$, ByVal Cnt&, ibsta%, iberr%, ibcntl&)
As Integer
C format: short WINAPI RSDLLilwrt( short ud, char far *Wrt,
unsigned long Cnt, short far *ibsta, short far *iberr, unsigned long far *ibcntl)
C format (Unix): short RSDLLilwrt( short ud, char *Wrt, unsigned long Cnt, short *ibsta, short *iberr,
unsigned long *ibcntl)
Parameter:
ud
Device handle
Wrt
String sent to the GPIB parser.
Cnt
Number of bytes sent to the device.
Example: RSDLLilwrt (ud, '......', 100, ibsta, iberr, ibcntl)
Like
RSDLLibwrt()
this function sends data to a device. The only difference is that binary data can be
sent as well. The length of the data is not determined by a zero-terminated string, but by the indication
of
Cnt
bytes. If the data is to be terminated with EOS (0Ah), the EOS byte must be appended to the
string.
RSDLLibwrtf
This function sends the contents of a file
file$
to the device with the handle
ud
.
VB format: Function RSDLLibwrtf (ByVal ud%, ByVal file$, 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 )
Parameter:
ud
Device handle
file
File the contents of which are sent to the device.
Example: RSDLLibwrtf(ud, "C:\db.sav", ibsta, iberr, ibcntl)
This function allows to send setting and query commands to the measuring instruments. Whether the
data is interpreted as complete command can be set using the function
RSDLLibeot()
.
RSDLLibrd()
The function reads data from the device with the handle
ud
into the string
Rd
.
