VB format: Function RSDLLibrd (ByVal ud%, ByVal Rd$, ibsta%, iberr%, ibcntl&) As Integer
C format: short WINAPI RSDLLibrd( short ud, char far *Rd, short far *ibsta, short far *iberr,
unsigned long far *ibcntl )
C format (Unix): short RSDLLibrd( short ud, char *Rd, short *ibsta, short *iberr, unsigned long *ibcntl
)
Parameter:
ud
Device handle
Rd
String into which the read data is copied.
Example: RSDLLibrd (ud, Rd, ibsta, iberr, ibcntl)
This function fetches the responses of the GPIB parser to a query.
In the case of Visual Basic programming, a string of sufficient length must be generated before. This
can be done during the definition of the string or using the command
Space$()
.
Generation of a string of the length 100:
- Dim Rd as String * 100
- Dim Rd as String
Rd = Space$(100)
RSDLLilrd
This function reads
Cnt
bytes from the device with the handle
ud
.
VB format: Function RSDLLilrd (ByVal ud%, ByVal Rd$, ByVal Cnt&, ibsta%, iberr%, ibcntl&) As
Integer
C format: short WINAPI RSDLLilrd( short ud, char far *Rd, unsigned long Cnt, short far *ibsta,
short far *iberr, unsigned long far *ibcntl )
C format (Unix): short RSDLLilrd( short ud, char *Rd, unsigned long Cnt, short *ibsta, short *iberr,
unsigned long *ibcntl )
Parameter:
ud
Device handle
cnt
Maximum number of bytes copied from the DLL into the target
string
Rd
.
Example: RSDLLilrd (ud, RD, 100, ibsta, iberr, ibcntl)
Like the function
RSDLLibrd()
, this function reads data from a device. The only difference is that in
this case the maximum number of bytes to be copied into the target string
Rd
can be indicated by
means of
Cnt
. This function prevents writing beyond the end of the string.
RSDLLibrdf()
Reads data from the device with the handle
ud
into the file
file
.
VB format: Function RSDLLibrdf (ByVal ud%, ByVal file$, ibsta%, iberr%, ibcntl&) As Integer
C format: short WINAPI RSDLLibrd( 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
