Description
===========

The Apache Traffic Server API provides large number of types. Many of them are
specific to a particular API function or function group, but others are used
more widely. Those are described on this page.

.. type:: ink_hrtime

.. type:: INK_MD5

   Buffer type sufficient to contain an MD5 hash value.

.. cpp:class:: INK_MD5

   See :type:`INK_MD5`.

.. cpp:class:: RecRawStatBlock

   A data block intended to contain |TS| statistics.

.. type:: TSAction

.. type:: TSCacheKey

.. type:: TSConfig

.. type:: TSConfigDestroyFunc

.. type:: TSCont

   An opaque type that represents a Traffic Server :term:`continuation`.

.. type:: TSEventFunc

.. type:: TSFile

.. type:: TSHostLookupResult

   A type representing the result of a call to :func:`TSHostLookup`. Use with :func:`TSHostLookupResultAddrGet`.

.. type:: TSHRTime

   "High Resolution Time"

   A 64 bit time value, measured in nanoseconds.

.. type:: TSHttpParser

.. type:: TSHttpSsn

   An opaque type that represents a Traffic SeUuirver :term:`session`.

.. type:: TSHttpTxn

   An opaque type that represents a Traffic Server HTTP :term:`transaction`.

.. type:: TSIOBuffer

.. type:: TSIOBufferBlock

.. type:: TSIOBufferReader

.. type:: TSIOBufferSizeIndex

.. type:: TSLifecycleHookID

   An enumeration that identifies a :ref:`life cycle hook <ts-lifecycle-hook-add>`.

.. type:: TSMBuffer

.. type:: TSMgmtCounter

.. type:: TSMgmtFloat

   The type used internally for a floating point value. This corresponds to the value :const:`TS_RECORDDATATYPE_FLOAT` for
   :type:`TSRecordDataType`.

.. type:: TSMgmtInt

   The type used internally for an integer. This corresponds to the value :const:`TS_RECORDDATATYPE_INT` for
   :type:`TSRecordDataType`.

.. type:: TSMgmtString

.. type:: TSMimeParser

.. type:: TSMLoc

.. var:: TSMLoc TS_NULL_MLOC

   A predefined null valued :type:`TSMLoc` used to indicate the absence of an :type:`TSMLoc`.

.. type:: TSMutex

.. type:: TSPluginRegistrationInfo

   The following struct is used by :func:`TSPluginRegister`.

   It stores registration information about the plugin.

.. type:: TSRemapInterface

.. type:: TSRemapRequestInfo

.. type:: TSSslX509

    This type represents the :code:`X509` object created from an SSL certificate.

.. type:: TSTextLogObject

   This type represents a custom log file that you create with
   :func:`TSTextLogObjectCreate`.

   Your plugin writes entries into this log file using
   :func:`TSTextLogObjectWrite`.

.. type:: TSThread

.. type:: TSThreadFunc

.. type:: TSUuidVersion

   A version value for at :type:`TSUuid`.

   .. member:: TS_UUID_V4

      A version 4 UUID. Currently only this value is used.

.. var:: size_t TS_UUID_STRING_LEN

   Length of a UUID string.

.. type:: TSVConn

    A virtual connection. This is the basic mechanism for abstracting I/O operations in |TS|.

.. type:: TSNetVConnection

    A subtype of :type:`TSVConn` that provides additional IP network information and operations.

.. type:: TSVIO

.. type:: ModuleVersion

    A module version.

.. cpp:type:: ModuleVersion

    A module version.

.. cpp:class:: template<typename T> DLL

    An anchor for a double linked instrusive list of instance of :arg:`T`.

.. cpp:class:: template<typename T> Queue

.. type:: TSAcceptor

.. type:: TSNextProtocolSet

.. cpp:class:: template <typename T> LINK

.. cpp:class:: VersionNumber

   A two part version number, defined in :ts:git:`include/tscore/I_Version.h`.

   .. cpp:member:: short int ink_major

      Major version number.

   .. cpp:member:: short int ink_minor

      Minor version number.
