newsticker--cache-contains

newsticker--cache-contains is a compiled Lisp function in `newst-backend.el'.

(newsticker--cache-contains DATA FEED TITLE DESC LINK AGE &optional GUID)

Check DATA whether FEED contains an item with the given properties.
This function returns the contained item or nil if it is not
contained.
The properties which are checked are TITLE, DESC, LINK, AGE, and
GUID. In general all properties must match in order to return a
certain item, except for the following cases.

If AGE equals 'feed the TITLE, DESCription and LINK do not
matter. If DESC is nil it is ignored as well. If
`newsticker-desc-comp-max' is non-nil, only the first
`newsticker-desc-comp-max' characters of DESC are taken into
account.

If GUID is non-nil it is sufficient to match this value, and the
other properties are ignored.
