Typedef Documentation

typedef struct _ADAPTER ADAPTER
 

Describes a network adapter.

This structure is the most important for the functioning of packet.dll, but the great part of its fields should be ignored by the user, since the library offers functions that avoid to cope with low-level parameters

typedef struct _ADAPTER * LPADAPTER
 

Describes a network adapter.

This structure is the most important for the functioning of packet.dll, but the great part of its fields should be ignored by the user, since the library offers functions that avoid to cope with low-level parameters

typedef struct _PACKET * LPPACKET
 

Structure that contains a group of packets coming from the driver.

This structure defines the header associated with every packet delivered to the application.

typedef struct NetType NetType
 

Network type structure.

This structure is used by the PacketGetNetType() function to return information on the current adapter's type and speed.

typedef struct npf_if_addr npf_if_addr
 

Addresses of a network adapter.

This structure is used by the PacketGetNetInfoEx() function to return the IP addresses associated with an adapter.

typedef struct _PACKET PACKET
 

Structure that contains a group of packets coming from the driver.

This structure defines the header associated with every packet delivered to the application.

typedef struct _PACKET_OID_DATA PACKET_OID_DATA* PPACKET_OID_DATA
