C format
(Unix)
short RSDLLibrd( short ud, char *Rd, short *ibsta, short *iberr,
unsigned long *ibcntl )
Parameters
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$, ByVal Cnt&, ibsta%,
iberr%, ibcntl&) As Integer
C-format
short WINAPI RSDLLilrd( short ud, char far *Rd, unsigned long Cnt,
short far *ibsta, short far *iberr, unsigned long far *ibcntl )
C format
(Unix)
short RSDLLilrd( short ud, char *Rd, unsigned long Cnt, short
*ibsta, short *iberr, unsigned long *ibcntl )
Parameters
ud
// Device handle
cnt //
Maximum number of bytes copied from the DLL into the target // string
Rd
.
Example
RSDLLilrd (ud, RD, 100, ibsta, iberr, ibcntl)
Like the function
RSDLLibrd()
, this function reads data from a device. The only difference is that in this
case the maximum number of bytes to be copied into the target string
Rd
can be indicated by means of
Cnt
. This function prevents writing beyond the end of the string.
RSDLLibrdf()
Reads data from the device with the handle
ud
into the file
file
.
VB format
Function RSDLLibrdf (ByVal ud%, ByVal file$, 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 )
