RSDLLWaitSrq
This function waits until the device triggers an SRQ with the handle ud.
VB format:
C format:
C format (UNIX):
Parameters:
Example:
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.
VB format:
C format:
C format (UNIX):
Parameters:
Example:
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.
