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 )
C format (Unix)
short RSDLLibrd( short ud, char *file, short *ibsta, short *iberr, unsigned long *ibcntl )
Parameters
ud // Device handle
file // File into which the read data is written
Example
RSDLLibrdf (ud, "c:\db.sav", ibsta, iberr, ibcntl)
The file name may as well include a drive or path specification.
RSDLLibtmo
This function defines the timeout for a device. The default value for the timeout is set to 5 seconds.
VB format
Function RSDLLibtmo (ByVal ud%, ByVal tmo%, ibsta%, iberr%, ibcntl&) As Integer
C-format
short WINAPI RSDLLibtmo( short ud, short tmo, short far *ibsta, short far *iberr,
unsigned long far *ibcntl )
C format
(Unix)
short RSDLLibtmo( short ud, short tmo, short *ibsta, short *iberr, unsigned long *ibcntl )
Parameters
ud // Device handle
tmo // Timeout in seconds
Example
RSDLLibtmo (ud, 10, ibsta, iberr, ibcntl)
