anonymous enum

Constants and bit masks for error codes. Enumeration values: Send_error  If this bit is set an error occurred in the send phase. Enot_existent  Receiver does not exist. Retimeout  Receive timeout. Setimeout  Send timeout. Recanceled  Receive canceled. Secanceled  Send canceled. Remapfailed  Receive mapping failed. Semapfailed  Send mapping failed. Resndpfto  Receive snd-page-fault timeout. Sesndpfto  Send snd-page-fault timeout. Rercvpfto  Receive receive-page-fault timeout. Sercvpfto  Send receive-page-fault timeout. Reaborted  Receive aborted. Seaborted  Send aborted. Remsgcut  Receive message cut. Semsgcut  Send message cut.

Constructor & Destructor Documentation

Ipc_err::Ipc_err (  Mword  raw = 0  )  [inline]

Create a error code from the binary representation. Parameters: raw  the binary representation of the error code.

---

Member Function Documentation

void Ipc_err::combine (  Ipc_err  other  )  [inline]

Combine two error codes. This method is for combining two error codes, this means the binary representations of the codes are or'd together. Parameters: other  the other error code to combine.

Mword Ipc_err::deceited (   )  const [inline]

Message was deceited? Returns: true if the message was deceited (the deceite bit is set).

void Ipc_err::error (  Mword  error  )  [inline]

Set the error code. Parameters: error  the error code to be set (see Error Codes). See also: error_code()

Mword Ipc_err::error (   )  const [inline]

Get the error code. Returns: The error code (see Error Codes).

void Ipc_err::fpage_received (  Mword  f  )  [inline]

Set/Clear the flex page received bit. Parameters: f  if true the bit is set or cleared else.

Mword Ipc_err::fpage_received (   )  const [inline]

Flexpage received? Returns: true if a flex page was received.

Mword Ipc_err::has_error (   )  const [inline]

Was there an error? Returns: true if there was any error.

Mword Ipc_err::raw (   )  const [inline]

Get the binary representation. Returns: The binary form of this error code.

Mword Ipc_err::rcv_map_failed (   )  const [inline]

Error == Receive map failed? Returns: true if error is receive map failed. See also: Error Codes

Mword Ipc_err::redirected (   )  const [inline]

Message redirected? Returns: The state of the redirect bit.

Mword Ipc_err::snd_error (   )  const [inline]

Was there a send error? Returns: true if there was a send error.

Mword Ipc_err::snd_map_failed (   )  const [inline]

Error == Send map failed? Returns: true if error is send map failed. See also: Error Codes

Mword Ipc_err::src_inside (   )  const [inline]

Source inside? Returns: The state of the source-inside bit.

char const * Ipc_err::str_error (   )  const

Return short word explaining the error. Returns: pointer to static string
