Detailed Description

MqEnvS - the class known as env or environment is used to store the protected environment in an service-call …

This struct hold parsed parts of the package-header and is guaranteed to be restored after the service-call.

• -> INCOMMING service call
  • -> SAVE struct MqEnvS
    • ... do some work...
  • <- RESTORE struct MqEnvS
• <- LEAVING service call
