wrapper for MkObjectHandleResolve with error-handline

Parameters

[in]

netHdl

The handle previously returned by MkObjectHandleGet.

Returns

Return an valid libmkkernel::MK_OBJ or MK_NULL with an error set.

• If netHdl is 0 than MK_NULL is returned and the upper-code decide how to deal with it.
• MkObjectHandleResolve return an valid libmkkernel::MK_OBJ or MK_NULL if the netHdl is invalid or the underlying object has already been deleted.
  • If a MK_NULL is returned than an error-message is created and a jump to the label error is done.
  • If a libmkkernel::MK_OBJ is returned than the netHdl is valid.

MkObjectGetNull()

static MK_OBJ libmkkernel::MkObjectGetNull ( void )

inlinestatic

Null-Slot - return a MkObjectC typed NULL instance …

Definition at line 3704 of file LibMkKernel_mk.h.

                                            {
    return (MK_OBJ)MK_NULL;
  }

Here is the caller graph for this function:

MkObjectHandleDelete_RT()

void libmkkernel::MkObjectHandleDelete_RT	(	MK_RT	mkrt,
		MK_OBJ const	netObj )

Handle-Delete-Slot - delete a netObj from handle-storage …

Here is the caller graph for this function:

MkObjectHandleDeleteByNetHdl_RT()

void libmkkernel::MkObjectHandleDeleteByNetHdl_RT	(	MK_RT	mkrt,
		MK_HDL const	netHdl )

Handle-Delete-Slot - delete a netHdl from handle-storage …

Here is the caller graph for this function:

MkObjectHandleExists()

bool libmkkernel::MkObjectHandleExists

(

MK_OBJ const

obj

)

check if obj has already a handle defined…

Parameters

[in]

obj

the MkObjectS instance to work on - a MANAGED OBJECT after type-check and able to be supported by the MkObjectS API

Returns

true or false

Here is the caller graph for this function:

MkObjectHandleGet_RT()

MK_HDL libmkkernel::MkObjectHandleGet_RT	(	MK_RT	mkrt,
		MK_OBJ const	obj )

Handle-Get-Slot - returns a export-hdl to the MkObjectC useable for external storage

The export-hdl is a reference to an instance that can be stored in software and converted back into an instance using the MkObjectHandleResolve.

By default, the export-hdl is initialized to "0", which is equivalent to does not exist. This function returns a non-zero and unique export-hdl that is recreated if necessary.

The export-hdl is only valid until the Programming-Language-Micro-Kernel (PLMK) ends.

example: The export-hdl is used in rpc to identify an object across the network.

Parameters

[in]	mkrt	the MkRuntimeS instance to work on - the runtime argument, used by MK_RT_CALL (C-only)
[in]	obj	the MkObjectS instance to work on - a MANAGED OBJECT after type-check and able to be supported by the MkObjectS API

Returns

the required export-hdl

Here is the caller graph for this function:

MkObjectHandleGetOfType()

static MK_HDL libmkkernel::MkObjectHandleGetOfType ( MK_OBJ const obj )

inlinestatic

Export-Slot - returns typeHdl of the obj .

A typeHdl identifies the type the obj belongs to. All instances of the same type share the same typeHdl.

Parameters

[in]

obj

the MkObjectS instance to work on - a MANAGED OBJECT after type-check and able to be supported by the MkObjectS API

Returns

the required typeHdl

Definition at line 3580 of file LibMkKernel_mk.h.

                                                                      {
  return ((MK_HDL)obj->signature);
}

Here is the caller graph for this function:

MkObjectHandleGetOr0()

MK_HDL libmkkernel::MkObjectHandleGetOr0

(

MK_OBJ const

obj

)

return export-hdl or 0 in not created…

Same as MkObjectHandleGet, but no new export-hdl is created if it has not already been created and the initial value 0 is returned instead.

Parameters

[in]

obj

the MkObjectS instance to work on - a MANAGED OBJECT after type-check and able to be supported by the MkObjectS API

Returns

the required export-hdl

Here is the caller graph for this function:

MkObjectHandleResolve_RT()

MK_OBJ libmkkernel::MkObjectHandleResolve_RT	(	MK_RT	mkrt,
		MK_HDL const	netHdl )

Handle-Resolve-Slot - return a MkObjectC from netHdl or MK_NULL if invalid…

The MkObjectHandleResolve undo the MkObjectHandleGet and is intended to export a unique identifer into external code not belonging to the Programming-Language-Micro-Kernel (PLMK).

Parameters

[in]	mkrt	the MkRuntimeS instance to work on - the runtime argument, used by MK_RT_CALL (C-only)
[in]	netHdl	handle former exported with MkObjectHandleGet

Returns

the required handle or MK_NULL if netHdl is invalid

Here is the caller graph for this function:

MkObjectInstances_RT()

static MK_OBJ libmkkernel::MkObjectInstances_RT ( MK_RT mkrt )

inlinestatic

get head-instance from linked-list of MkObjectS type …

The head-instance is the last instance created.
