EXPRESSION structure

The EXPRESSION structure contains a group of ANDEXP arrays evaluated as peers in logical AND expressions, which have the format

(ANDEXP 1 && ANDEXP 2 && ANDEXP 3).

Syntax

typedef struct _EXPRESSION {
  DWORD  nAndExps;
  ANDEXP AndExp[MAX_PATTERNS];
} EXPRESSION, *LPEXPRESSION;

Members

nAndExps

Number of ANDEXP patterns.

AndExp

Array of ANDEXP patterns. The capture filter arranges all rows of this array as logical AND statements. Be aware that each EXPRESSION structure can contain a maximum of four ANDEXP patterns.

Remarks

For more information about implementing this structure as part of a capture filter, see Capture Filters.
