mqput message identifier

[maddogpat]

hello,

i need to replace the default message id with a specific requirement. I understand the byte concept etc, but how do I actually change the value in c? I know MQMI_NONE sets it to the default.

memcpy(md.MsgId, MQMI_NONE, sizeof(md.MsgId) );

How would I now insert my own value?

any help much appreciated!

thanks

memcpy(md.MsgId, MQMI_NONE, sizeof(md.MsgId) );
memcpy(md.MsgId, yourvalue, sizeof(yourvalue) );

The first line clears out message-id, the second line populates it with yourvalue. If yourvalue is always 24 bytes, then you don't need the first line.
