       TSAPI Types - TSTypes API function

SYNOPSIS

          #include <ts/ts.h>
          #include <ts/remap.h>

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.

       class INK_MD5
              See INK_MD5.

       class RecRawStatBlock
              A data block intended to contain Traffic Server statistics.

       type TSAction

       type TSCacheKey

              An opaque type that represents a Traffic Server continuation.

       type TSEventFunc

       type TSFile

       type TSHostLookupResult
              A   type   representing   the   result  of  a  call  to  TSHostLookup().  Use  with
              TSHostLookupResultAddrGet().

       type TSHRTime
              "High Resolution Time"

              A 64 bit time value, measured in nanoseconds.

       type TSHttpConnectOptions
              A type that encapsulates options passed into the TSHttpConnectPlugin() function.

              TSConnectType connect_type
                     The type of data represented in the struct.

              sockaddr const *addr
                     Network address of the target of the connection.

              const char *tag
                     Tag that is passed through to the HTTP state machine.

              int64_t id
                     Numeric identifier passed through to the HTTP state machine.

              TSIOBufferSizeIndex buffer_index
                     A  numeric  buffer  size  index  used  to  derive  actual  sizes  used  when
                     constructing IOBuffers; see TSIOBufferSizeIndex.

              TSIOBufferWaterMark buffer_water_mark
                     A  numeric value specifying the minimum number of bytes that must be written
                     to an IOBuffer before any continuation is  called  back  to  read  from  the
                     buffer.    See  the  TSIOBufferWaterMarkGet()  and  TSIOBufferWaterMarkSet()
                     functions for further detail.

       type TSConnectType
              Enumeration  that  specifies  the  type  of  data  within  a   TSHttpConnectOptions
              structure.

       type TSHttpParser

       type TSHttpSsn
              An opaque type that represents a Traffic Server session.

       type TSHttpTxn
              An opaque type that represents a Traffic Server HTTP transaction.

       type TSIOBuffer

       type TSIOBufferBlock

       type TSIOBufferReader

       type TSIOBufferSizeIndex

       type TSIOBufferWaterMark
              An enumeration that contains valid watermark values, currently only defaults.

       type TSLifecycleHookID
              An enumeration that identifies a life cycle hook.

       type TSMBuffer
              Internally, data for a transaction is stored in one or more header heaps. These are
              storage local to the transaction, and generally each HTTP header  is  stored  in  a
              separate  one.  This type is a handle to a header heap, and is provided or required
              by functions that locate HTTP header related data.

       type TSMgmtCounter

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

       type TSMgmtInt
              The   type   used  internally  for  an  integer.  This  corresponds  to  the  value
              TS_RECORDDATATYPE_INT for TSRecordDataType.

       type TSMgmtString

       type TSMimeParser

       type TSMLoc
              This is a memory location relative to a header heap represented by a TSMBuffer  and
              must  always  be  used in conjunction with that TSMBuffer instance. It identifies a
              specific object in the TSMBuffer. This indirection is needed so that the  TSMBuffer
              can  reallocate  space  as  needed.  Therefore a raw address obtained from a TSMLoc
              should be considered volatile that may become invalid across any API call.

       TSMLoc TS_NULL_MLOC
              A predefined null valued TSMLoc used to indicate the absence of an TSMLoc.

       type TSMutex

       type TSPluginRegistrationInfo
              The following struct is used by TSPluginRegister().

              It stores registration information about the plugin.

       type TSRemapInterface
              Data passed to a remap plugin via TSRemapInit().

              unsigned long size
                     The size of the structure in bytes, including this member.

              unsigned long tsremap_version
                     The API version of the C API. The lower 16 bits are the minor  version,  and
                     the upper bits the major version.

       type TSRemapRequestInfo
              Data passed to a remap plugin during the invocation of a remap rule.

              TSMBuffer requestBufp
                     The  client  request.  All  of  the other TSMLoc values use this as the base
                     buffer.

              TSMLoc requestHdrp
                     The client request.

              TSMLoc mapFromUrl
                     The match URL in the remap rule.

              TSMLoc mapToUrl
                     The target URL in the remap rule.

              TSMLoc requestUrl
                     The current request URL. The remap rule and plugins listed  earlier  in  the
                     remap  rule  can  modify this from the client request URL. Remap plugins are
                     expected to modify this value to perform the remapping of the request.  Note
                     this    is   the   same   TSMLoc   as   would   be   obtained   by   calling
                     TSHttpTxnClientReqGet().

              int redirect
                     Flag for using the remapped URL as an explicit redirection. This can be  set
                     by the remap plugin.

       type TSSecretID
              Contains the data for a TLS certificate and key.

              const char *cert_name;
                     The TLS certificate name.

              size_t cert_name_len;
                     The length of the TLS certificate name.

              const char *key_name;
                     The name of the TLS key.

              size_t key_name_len;
                     The length of the name of the TLS key.

       type TSSslX509
              This type represents the X509 object created from an SSL certificate.

       type TSTextLogObject
              This    type    represents    a    custom   log   file   that   you   create   with
              TSTextLogObjectCreate().

              Your plugin writes entries into this log file using TSTextLogObjectWrite().

       type TSThread
              This represents an internal Traffic Server thread, created by  the  Traffic  Server
              core.  It  is  an  opaque  type  which  can  be  used  only to check for equality /
              inequality, and passed to API functions. An instance that  refers  to  the  current
              thread can be obtained with TSThreadSelf().

       type TSEventThread
              This  type  represents  an event thread. It is an opaque which is used to specify a
              particular event processing thread in Traffic Server. If plugin code  is  executing
              in  an event thread (which will be true if called from a hook or a scheduled event)
              then the current event thread can be obtained via TSEventThreadSelf().

              A TSEventThread is also a TSThread  and  can  be  passed  as  an  argument  to  any
              parameter of type TSThread.

       type TSThreadFunc

       type TSUserArgType
              An enum for the supported types of user arguments.

       enum TSUuidVersion
              A version value for at TSUuid.

              enumerator TS_UUID_V4
                     A version 4 UUID. Currently only this value is used.

       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
              Traffic Server.

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

       type TSVIO

       type ModuleVersion
              A module version.

       type ModuleVersion
              A module version.

       template<typename T> class DLL
              An anchor for a double linked intrusive list of instance of T.

       template<typename T> class Queue

       type TSAcceptor

       template<typename T> class LINK

       class VersionNumber
              A two part version number, defined in include/tscore/I_Version.h.

              short int ink_major
                     Major version number.

              short int ink_minor
                     Minor version number.

       type TSFetchUrlParams_t

       type TSFetchSM

       type TSFetchEvent

       type TSHttpPriority
              The abstract type of the various HTTP priority implementations.

              uint8_t priority_type
                     The  reference  to the concrete HTTP priority implementation. This will be a
                     value from TSHttpPriorityType

              uint8_t data[7]
                     The space allocated for the concrete priority implementation.

                     Note that this has to take padding into account. There is a static_assert in
                     InkAPI.cc   to   verify   that  TSHttpPriority  is  at  least  as  large  as
                     TSHttp2Priority. As other structures  are  added  that  are  represented  by
                     TSHttpPriority  add  more static_asserts to verify that TSHttpPriority is as
                     large as it needs to be.

       type TSHttp2Priority
              A structure for HTTP/2 priority. For an explanation of these terms with respect  to
              HTTP/2, see RFC 7540, section 5.3.

              uint8_t priority_type
                     HTTP_PROTOCOL_TYPE_HTTP_2

              uint8_t weight

              int32_t stream_dependency
                     The  stream dependency. Per spec, see RFC 7540 section 6.2, this is 31 bits.
                     We use a signed 32 bit structure to store either a valid dependency or -1 if
                     the stream has no dependency.
