Detailed Description

Author

Breno Silva breno.nosp@m..sil.nosp@m.va@gm.nosp@m.ail..nosp@m.com

Victor Julien victo.nosp@m.r@in.nosp@m.linia.nosp@m.c.ne.nosp@m.t

Implements the threshold keyword.

The feature depends on what is provided by detect-engine-threshold.c and util-threshold-config.c

Definition in file detect-threshold.c.
