ufoProcessIsRasterInDirty

    int ufoProcessIsRasterInDirty(
       ufoProcess process_instance,
       int input_index);

ufoProcesslsRasterInDirty returns a value of 1 if input is dirty and a value of 0 if input is not dirty.

Inquire if raster input is dirty. An input is not dirty if it hasn’t changed since the last render and its dirty status was reset with ufoProcessResetRasterInDirty. This may occur during consecutive renders at the same frame during interactive editing, or if there is a hold (or freeze) on the input in a sequence.
