Buffer (MQBYTExBufferLength) - input

This is a buffer containing the application data to be sent. The buffer must be aligned on a boundary appropriate to the nature of the data in the message. 4-byte alignment is suitable for most messages (including messages containing MQ header structures), but some messages might require more stringent alignment. For example, a message containing a 64-bit binary integer might require 8-byte alignment.

If Buffer contains character or numeric data, set the CodedCharSetId and Encoding fields in the MsgDesc parameter to the values appropriate to the data; this enables the receiver of the message to convert the data (if necessary) to the character set and encoding used by the receiver.

Note:

All the other parameters on the MQPUT call must be in the character set and encoding of the local queue manager (given by the CodedCharSetId queue-manager attribute and MQENC_NATIVE).

In the C programming language, the parameter is declared as a pointer-to-void; the address of any type of data can be specified as the parameter.

If the BufferLength parameter is zero, Buffer is not referred to; in this case, the parameter address passed by programs written in C or System/390 assembler can be null.
