The TCP_BOOLEAN_OPTIONAL enumeration defines the states that a caller can specify when updating a member in the read/write information for a TCP connection.
Syntax
typedef enum _TCP_BOOLEAN_OPTIONAL {
TcpBoolOptDisabled = 0,
TcpBoolOptEnabled,
TcpBoolOptUnchanged = -1
} TCP_BOOLEAN_OPTIONAL, *PTCP_BOOLEAN_OPTIONAL;
Constants
TcpBoolOptDisabledValue: 0 The option should be disabled. |
TcpBoolOptEnabledThe option should be enabled. |
TcpBoolOptUnchangedValue: -1 The option should be unchanged. |
Remarks
The TCP_BOOLEAN_OPTIONAL enumeration is defined on Windows Vista and later.
The collection of extended statistics on a TCP connection are enabled and disabled using calls to the SetPerTcp6ConnectionEStats and SetPerTcpConnectionEStats functions where the type of extended statistics specified is one of values from the TCP_ESTATS_TYPE enumeration type. A value from the TCP_BOOLEAN_OPTIONAL enumeration is used to specify how a member in the TCP_ESTATS_BANDWIDTH_RW_v0 structure should be updated to enable or disable extended statistics on a TCP connection for bandwidth estimation.
