Data Parameter

The

data

parameter is deﬁned as a byte array. It can be in one of two

formats: either holding the actual data or in a vectored format. In the

case of vectored data, the

data

parameter does not contain actual data

but rather the addresses from or to which the data will be gathered or

distributed.

The addresses of the data are represented by data location descriptors.

For all intrinsics supporting vectored data, a maximum of two data

location descriptors is permitted.

For vectored data, the parameter must be a record structured as

described below. The format of a compatibility mode data location

descriptor is different than a native mode data location descriptor as

shown in Figure 3-3.

Combining a compatibility mode vector with a native mode vector in the

same NetIPC call is not supported.
