result Reference to an integer value in which the library returns the
status of the SRQ bit.
0 - No SRQ has occurred during the timeout
1 - SRQ has occurred during the timeout
Beispiel: RSDLLWaitSrq( ud, result, ibsta, iberr, ibcntl );
The function waits until one of the following two events occurs.
The measuring instrument triggers an SRQ
No SRQ occurs during the timeout defined with RSDLLibtmo()
RSDLLSwapBytes
This function changes the display of binary numbers on non-Intel platforms.
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)
Parameter: 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))
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.
Different types of processor architecture store data in different byte sequences. For example, Intel
processors store data in the reverse order of Motorola processors. Comparison of byte sequences:
Byte
sequence
Use in Display in memory Description
Big Endian Motorola processors,
network standard
Most significant byte at least
significant address
The most significant byte is at the left
end of the word.
Little Endian Intel processors Least significant byte at least
significant address
The most significant byte is at the right
end of the word.
