RSDLLWaitSrq
This function waits until the device triggers an SRQ with the handle
ud
.
The function waits until one of the following two events occurs.
• The measuring instrument triggers an SRQ.
• No SRQ occurs during the time-out defined with
RSDLLibtmo().
RSDLLSwapBytes
This function changes the display of binary numbers on non-Intel platforms.
This function swaps the display of various elements from Big Endian to Little Endian
and vice versa. It is expected that a coherent storage area of elements of the same
file type (
size
byte) is transferred to
pArray
. This function has no effect on Intel
platforms.
VB format:
Function RSDLLWaitSrq (ByVal ud%, Result%,
ibsta%, iberr%, ibcntl&) As Integer
C format:
void WINAPI RSDLLWaitSrq( short ud, short
far *result, short far *ibsta, short far
*iberr, unsigned long far *ibcntl)
C format (UNIX):
short RSDLLWaitSrq( short ud, short
*result, short *ibsta, short *iberr,
unsigned long *ibcntl)
Parameters:
ud
Device handle
result
Reference to an integer value in which
the library returns the status of the
SRQ bit
0 - No SRQ occurred during the time-
out
1 - SRQ occurred during the time-out
Example:
RSDLLWaitSrq( ud, result, ibsta, iberr,
ibcntl );
VB format:
Not provided at present since it is
required only on non-Intel platforms.
C format:
void WINAPI RSDLLSwapBytes( void far
*pArray, const long size, const long count)
C format (UNIX):
void RSDLLSwapBytes( void *pArray, const
long size, const long count)
Parameters:
pArray
Array in which modifications are made
size
Size of a single element in
pArray
count
Number of elements in
pArray
Example:
RSDLLSwapBytes( Buffer, sizeof(float),
ibcntl/sizeof(float))
