the entry point to the send packet routine for an MPCI implementation.
rtems_mpci_table is the data structure
containing the configuration information for an MPCI.
rtems_name is the data type used to
contain the name of a Classic API object. It is an unsigned
thirty-two bit integer which can be treated as a numeric
value or initialized using rtems_build_name to
contain four ASCII characters.
rtems_option is the data type
used to specify which behavioral options the caller desires.
It is commonly used with potentially blocking directives to specify
whether the caller is willing to block or return immediately with an error
indicating that the resource was not available.
rtems_packet_prefix is the data structure
that defines the first bytes in every packet sent between nodes
in an RTEMS multiprocessor system. It contains routing information
that is expected to be used by the MPCI layer.
rtems_signal_set is the data
type used to manage and manipulate RTEMS signal sets
with the Signal Manager.
int8_t is the C99 data type that corresponds to signed eight
bit integers. This data type is defined by RTEMS in a manner that
ensures it is portable across different target processors.
int16_t is the C99 data type that corresponds to signed
sixteen bit integers. This data type is defined by RTEMS in a manner
that ensures it is portable across different target processors.
int32_t is the C99 data type that corresponds to signed
thirty-two bit integers. This data type is defined by RTEMS in a manner
that ensures it is portable across different target processors.
int64_t is the C99 data type that corresponds to signed
sixty-four bit integers. This data type is defined by RTEMS in a manner
that ensures it is portable across different target processors.
rtems_single is the RTEMS data
type that corresponds to single precision floating point
on the target hardware.
This type is deprecated. Use "float" instead.
rtems_status_codes is the
rtems_task is the return type for an
RTEMS Task.
rtems_task_argument is the data
type for the argument passed to each RTEMS task. In RTEMS 4.7
and older, this is an unsigned thirty-two bit integer. In
RTEMS 4.8 and newer, this is based upon the C99 type uintptr_t
which is guaranteed to be an integer large enough to hold a
pointer on the target architecture.
rtems_task_begin_extension is the
entry point for a task beginning execution user extension handler routine.
rtems_task_create_extension is the
entry point for a task creation execution user extension handler routine.
rtems_task_delete_extension is the
entry point for a task deletion user extension handler routine.
rtems_task_entry is the address of
the entry point to an RTEMS ASR. It is equivalent to the
entry point of the function implementing the ASR.
rtems_task_exitted_extension is the
entry point for a task exitted user extension handler routine.

eight bit integers. This data type is defined by RTEMS in a manner that
ensures it is portable across different target processors.
uint16_t is the C99 data type that corresponds to unsigned
sixteen bit integers. This data type is defined by RTEMS in a manner
that ensures it is portable across different target processors.
uint32_t is the C99 data type that corresponds to unsigned
thirty-two bit integers. This data type is defined by RTEMS in a manner
