INET_PORT_RANGE structure (mstcpip.h)

The INET_PORT_RANGE structure provides input data used by the SIO_ACQUIRE_PORT_RESERVATION IOCTL to acquire a runtime reservation for a block of TCP or UDP ports.

Syntax

typedef struct _INET_PORT_RANGE {
  USHORT StartPort;
  USHORT NumberOfPorts;
} INET_PORT_RANGE, *PINET_PORT_RANGE, INET_PORT_RESERVATION, *PINET_PORT_RESERVATION;

Members

StartPort

The starting TCP or UDP port number. If this parameter is set to zero, the system will choose a starting TCP or UDP port number.

NumberOfPorts

The number of TCP or UDP port numbers to reserve.

Remarks

The INET_PORT_RANGE structure is supported on Windows Vista and later.

The INET_PORT_RANGE structure is the datatype passed in the input buffer to the SIO_ACQUIRE_PORT_RESERVATION IOCTL. This IOCTL is used to acquire a runtime reservation for a block of TCP or UDP ports.

The INET_PORT_RANGE structure is typedefed to the INET_PORT_RESERVATION structure.
