The
tokens
parameter is a structure that contains a field for every token,
including tokens not used on the current connection. To request a token from the
remote application, set the corresponding value in the structure to ZAPS-VAL-
TOKEN-PLEASE. Set all of the other token fields to ZAPS-VAL-TOKEN-
NOVALUE.
The maximum amount of user data you can send with this primitive depends on
the layer of your connection, whether you are using session version 1 or session
version 2, and (for presentation and ACSE connections) whether your connection
is in normal mode or X.410-1984 mode. The maximum length of the
user-data
parameter is as follows:
Session version 1 Session version 2
Session connection 512 bytes 10240 bytes
Presentation connection (normal mode) <512 bytes < 10240 bytes
ACSE connection (normal mode) <512 bytes < 10240 bytes
For a normal-mode presentation or ACSE connection, you can send as much data
as will fit in a 512-byte PPDU (for session version 1) or a 10240-byte PPDU (for
session version 2); the maximum length depends on the encoding.
For a presentation or ACSE connection in X.410-1984 mode, the maximum amount
of data is the same as that for a session connection.
