(PalmOS 3.0)
Let's suppose I have 2 applications: Receiver (that receives messages via
PagerCard or something else) and Viewer (used to view result dependent on
received message). When Viewer is active application and new message
arrives, Receiver is trigged by special action code, receives message,
refreshes DB and sends MY CUSTOM action code to Viewer to notify that.
My custom action code is defined 'by the book' as
sysAppLaunchCmdCustomBase.
Receiver sends it via
SysBroadcastActionCode()
API call and Viewer handles it well.
Now, since sysAppLaunchCmdCustomBase is only some *number* in fact and
SysBroadcastActionCode() sends it to *ALL* UI applications, what
would happen if there is some other application on same Palm that has
defined that same *number* as action code and sends it or responds to it?
CmdPBP is definitely wrong in such situation and it may cause app to
crash.
How to handle such situations (risk of overlap custom launch codes for
different apps) in general?
Rgds,
