ENUMERATION_BUFFER structure (traffic.h)

The ENUMERATION_BUFFER structure contains information specific to a given flow, including flow name, the number of filters associated with the flow, and an array of filters associated with the flow.

Syntax

typedef struct _ENUMERATION_BUFFER {
  ULONG         Length;
  ULONG         OwnerProcessId;
  USHORT        FlowNameLength;
  WCHAR         FlowName[MAX_STRING_LENGTH];
  PTC_GEN_FLOW  pFlow;
  ULONG         NumberOfFilters;
  TC_GEN_FILTER GenericFilter[1];
} ENUMERATION_BUFFER, *PENUMERATION_BUFFER;

Members

Length

Number of bytes from the beginning of the ENUMERATION_BUFFER to the next ENUMERATION_BUFFER.

OwnerProcessId

Identifies the owner of the process.

FlowNameLength

Specifies the length of the FlowName member.

FlowName[MAX_STRING_LENGTH]

Array of WCHAR characters, of length MAX_STRING_LENGTH, that specifies the flow name.

pFlow

Pointer to the corresponding TC_GEN_FLOW structure. This structure is placed immediately after the array of TC_GEN_FILTERS and is included in Length.

NumberOfFilters

Specifies the number of filters associated with the flow.

GenericFilter[1]

Array of TC_GEN_FILTER structures. The number of elements in the array corresponds to the number of filters attached to the specified flow. Note that in order to enumerate through the array of TC_GEN_FILTER structures, you need to increment the pointer to the current TC_GEN_FILTER by using the following:

sizeof(TC_GEN_FILTER) + 2 * [the pattern size of the current TC_GEN_FILTER structure].
