int DetectVarStoreMatch(DetectEngineThreadCtx *, uint32_t, uint8_t *, uint16_t, int)
Store flowvar in det_ctx so we can exec it post-match.

void DetectFlowvarRegister(void)
int DetectFlowvarPostMatchSetup(Signature *s, uint32_t idx)
Setup a post-match for flowvar storage We&#39;re piggyback riding the DetectFlowvarData struct...
void DetectVarProcessListInternal(DetectVarList *fs, Flow *f, Packet *p)
Handle flowvar candidate list in det_ctx: clean up the list.
