If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

Notes

Excessive Stack Depth warnings are associated with the function call that causes stack depth to be exceeded.

For user-defined functions, the warning is issued at the entry point of the called function.
For library functions and undefined functions, the warning is issued at the call site.

Important configuration file parameters for this warning class are:

STACK_DEPTH_THRESHOLD	The call stack size (in bytes) beyond which a warning will be issued.
STACK_DEPTH_UNDEFINED_FUNCTION_SIZE, STACK_DEPTH_COMPILER_PADDING, STACK_DEPTH_ACTIVATION_RECORD_CONSTANTS	Allow users to specify estimates of the amount of call stack space required for various program artifacts.

Relevant Configuration File Parameters

The following configuration file parameters affect checks for this warning class.
