RSDLLibrd()
The function reads data from the instrument into the string Rd with the handle ud.
VB format: Function RSDLLibrd (ByVal ud%, ByVal Rd$, ibsta%, iberr%,
ibcntl&) As Integer
C format: short FAR PASCAL RSDLLibrd( short ud, char far *Rd, short far
*ibsta, short far *iberr, unsigned long far *ibcntl )
C format (Unix): short RSDLLibrd( short ud, char *Rd, short *ibsta, short
*iberr, unsigned long *ibcntl )
Parameter: ud Device handle
Rd String into which the read data are copied.
Example: RSDLLibrd (ud, Rd, ibsta, iberr, ibcntl)
This function fetches replies of the IEC/IEEE-bus parser in response to a query command.
For this, a string of sufficient length must be generated when programming in Visual Basic. This can be
accomplished in the definition of the string or with the command Space$().
Generation of a string of the length 100: - Dim Rd as String * 100
- Dim Rd as String
Rd = Space$(100)
RSDLLilrd
The function reads Cnt bytes from the instrument with the handle ud.
VB format: Function RSDLLilrd (ByVal ud%, ByVal Rd$, ByVal Cnt&, ibsta%,
iberr%, ibcntl&) As Integer
C format: short FAR PASCAL RSDLLilrd( short ud, char far *Rd, unsigned
long Cnt, short far *ibsta, short far *iberr, unsigned long
far *ibcntl )
Parameter: ud Device handle
cnt Maximum number of bytes copied to target string Rd by the
DLL.
Example: RSDLLilrd (ud, RD, 100, ibsta, iberr, ibcntl)
The function reads data from an instrument same as function RSDLLibrd() but with the difference that
here the maximum number of bytes is allowed to be copied to target string Rd to be defined with Cnt.
Writing beyond a string can thus be prevented with this function. The number of bytes cut off is lost.
RSDLLibrdf()
Reads data from the instrument into the file file with the handle ud.
VB format: Function RSDLLibrdf (ByVal ud%, ByVal file$, ibsta%, iberr%,
ibcntl&) As Integer
C format: short FAR PASCAL RSDLLibrdf( short ud, char far *file, short
far *ibsta, short far *iberr, unsigned long far *ibcntl )
C format (Unix): short RSDLLibrd( short ud, char *file, short *ibsta, short
*iberr, unsigned long *ibcntl )
Parameter: ud Device handle
file File into which the read data are written.
Example: RSDLLibrdf (ud, c:\db.sav, ibsta, iberr, ibcntl)
This function serves to read replies of the IEC/IEEE-bus parser that are larger than 64 KB. The file
name may include the drive and path.
