texinfo-find-higher-level-node

texinfo-find-higher-level-node is a compiled Lisp function in `texnfo-upd.el'.

(texinfo-find-higher-level-node LEVEL REGION-END)

Search forward from point for node at any higher level than argument LEVEL.
Search is limited to the end of the marked region, REGION-END.

Return t if the node is found, else nil. Leave point at the beginning
of the node if one is found; else do not move point.

A `@node' line starting at point does count as a match;
if the match is found there, the value is t and point does not move.
