This function retrieves the IPv4 TCP connection table.

Syntax

ULONG WINAPI GetTcpTable2(
  __out    PMIB_TCPTABLE2 TcpTable,
  __inout  PULONG SizePointer,
  __in     BOOL Order
);

Parameters

TcpTable
A pointer to a buffer that receives the TCP connection table as a MIB_TCPTABLE2 structure.

SizePointer
On input, specifies the size of the buffer pointed to by the TcpTable parameter.

On output, if the buffer is not large enough to hold the returned connection table, the function sets this parameter equal to the required buffer size.

Order
A value that specifies whether the TCP connection table should be sorted. If this parameter is TRUE, the table is sorted in the order of:
1. Local IP address
2. Local port
3. Remote IP address
4. Remote port

Return Value

If the function succeeds, the return value is NO_ERROR.

If the function fails, the return value is one of the following error codes.

Return code	Description
ERROR_INSUFFICIENT_BUFFER	The buffer pointed to by the TcpTable parameter is not large enough. The required size is returned in the PULONG variable pointed to by the SizePointer parameter. This error is also returned if the pTcpTable parameter is NULL.
ERROR_INVALID_PARAMETER	The SizePointer parameter is NULL, or GetTcpTable2 is unable to write to the memory pointed to by the SizePointer parameter.
ERROR_NOT_SUPPORTED	This function is not supported on the operating system that is used on the local system.
Other	Use FormatMessage to obtain the message string for the returned error.

Remarks

The GetTcpTable2 function is an increased version of the GetTcpTable function that also retrieves information on the TCP offload state of the TCP connection.
