Function Documentation

void QFsm_init

(

QFsm *

me

)

Initializes a FSM.

Takes the top-most initial transition in a FSM.

Parameters:

me

is the pointer the state machine structure derived from FHsm.

Note:

Must be called only ONCE after QFsm_ctor() and before any calls to QFsm_dispatch().

Definition at line 63 of file qepn.c.

void QHsm_init

(

QHsm *

me

)

Initializes a HSM.

Takes the top-most initial transition in a HSM.

Parameters:

me

is the pointer the state machine structure derived from QHsm.

Note:

Must be called only ONCE after QHsm_ctor() and before any calls to QHsm_dispatch().

QState QHsm_top

(

QHsm *

me

)

The top-state.

QHsm_top() is the ultimate root of state hierarchy in all HSMs derived from QHsm. This state handler always returns (QState)0, which means that it "handles" all events.

Example of the QCalc_on() state handler for Q_INIT().

char const Q_ROM* Q_ROM_VAR QP_getVersion

(

void

)

get the current QP version number string

Returns:

version of the QP-nano as a constant 6-character string of the form X.Y.ZZ, where X is a 1-digit major version number, Y is a 1-digit minor version number, and ZZ is a 2-digit release number.
