Pointer to a structure, which describes the configuration of one or more UDP ports.
typedef struct {

ul_PortCount;
TY_FDX_BLOCK_READ_IN_PORT* px_UdpBlockReadInPortArray;
} TY_FDX_UDP_BLOCK_READ_IN;

Pointer to an array of structures. Each structure describes an individual read operation for a
single UDP port. The array contains ul_PortCount elements.
typedef struct {
AiUInt32
ul_UdpHandle;
AiUInt32 ul_MsgCount;
}TY_FDX_UDP_BLOCK_READ_IN;
A A i i U U I I n n t t 3 3 2 2 u u l l _ _ U U d d p p H H a a n n d d l l e e
The handle of the UDP port to which the message(s) will be written. This can be a handle
to either a Sampling or Queuing port.
A A i i U U I I n n t t 3 3 2 2 u u l l _ _ M M s s g g C C o o u u n n t t
Reserved. (Number of Messages to read. Value of this parameter is ignored and set
internal to 1. )
Have also a look to the output parameter section for variables used there as input!
Note: For all port types the number of messages to read shall be always 1. To read
more messages of one port (queuing type only) add another entry to input array
px_UdpBlockReadInPortArray with same ul_UdpHandle.
