RE: TCP/IP Sockets - Send length problem

[Chris Bipes <chris.bipes@xxxxxxxxxxxxxxx>]

Generally in Sockets C API's you need to null terminate the string.  In
RPGLE you need to append a Null to the end of your string.  Are you sure
they are receiving nulls or some other garbage?  Have them check the hex
codes of the data they are receiving.  You can also check your parm in the
prototype.  Define the variable there as variable length with the option
*STRING.  This tells the compiler to automatically append the Null to the
string.

d Write           PR            10i 0 ExtProc('write')

d                               10i 0 Value
SocketDId
d                                 *   Value
PtrToBuffer

Subject: TCP/IP Sockets - Send length problem

We have a sockets application on the AS/400 that is talking to a PC based
application running under Windows sockets.  Our interface is working well,
except for one small problem.  The SocketData field that holds the data
portion of the packet is defined as a variable length field and we specify
the length (%len) of the data string on the send function, but no matter
what we do, we can't get the program to send the actual length of data down
the line.  The customer is getting our data string followed by a bunch of
"@" (nulls) out to the end of the transmission.
