Owning Palette: File-Based Write Filter VIs

Requires: DSC Module or Touch Panel Module

Changes the file-based write filter (FBWF) cache configuration parameters, such as whether to compress the FBWF cache and whether to preallocate RAM space for the cache.

Note  You must restart the operating system for changes to take effect.

Example

size limit specifies the maximum size, in megabytes, of the FBWF cache. The valid range is [16, 1024].
compress on? specifies whether to compress the cache to meet the size limit. When compress on? is FALSE, the cache does not compress. If compress on? is TRUE, the cache compresses to meet the size limit. You cannot enable compress on? and preallocate on? at the same time. If you specify TRUE for both controls, this VI disables compress on? and enables preallocate on?.
preallocate on? specifies whether to enable or disable the cache preallocation. If preallocate on? is FALSE, the cache dynamically allocates RAM space. When preallocate on? is TRUE, the cache preallocates RAM space. You cannot enable compress on? and preallocate on? at the same time. If you specify TRUE for both controls, this VI disables compress on? and enables preallocate on?.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
error out contains error information. This output provides standard error out functionality.
