nn::fs::InitializeLatencyEmulation Function

void InitializeLatencyEmulation(
     void
);

None.

None.

Initializes the feature for emulating the behavior of a non-volatile memory device that has become degraded, and the behavior when a conflict arises for FS resources with a process in the background.

Be absolutely sure to call this initialization function because the emulation feature cannot be enabled unless you do.
You can enable/disable this feature in the Config settings.
In the retail product environment, this feature is invariably disabled, so there is no problem including a call to this function in the product code.

Total latency is the sum of the routinely-applied delay time plus a random delay time determined separately for each access event.
A randomly determined delay time is enabled only if the debug mode setting is enabled by Config.
For each Read/TryRead, the range is 0 ms to 100 ms. For each Write/TryWrite, the range is 0 ms to 380 ms. If disabled, it is 0.
The routinely-applied delay time takes the value configured in the FS Latency Emulation settings in Config.

The table shows latency times in the development environment.

Config settings		Delay time
Debug Mode	FS Latency Emulation
enable	Some time other than 0 ms	Random delay + routine delay
enable	0 ms	Random delay only
disable	Some time other than 0 ms	Routine delay only
disable	0 ms	None
