Accessing CP special messages through uevent environment variables
A uevent for a CP special message contains environment variables that you can use to access the message.
- SMSG_ID
- Specifies the message prefix. The SMSG_ID environment variable is always set to APP, which is the prefix that is assigned to the smsgiucv_app device driver.
- SMSG_SENDER
- Specifies the z/VM user
ID that sent the CP special message.
Use SMSG_SENDER in udev rules for filtering the z/VM user ID if you want to accept CP special messages from different senders. All alphabetic characters in the z/VM user ID are uppercase characters.
- SMSG_TEXT
- Contains the message text of the CP special message. The APP prefix and leading white spaces are removed.
