wrapper for MkBufferStreamHandleResolve with error-handline

Parameters

[in]

netHdl

The handle previously returned by MkObjectHandleGet.

Returns

Return an valid libmkkernel::MK_BUS 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.
• MkBufferStreamHandleResolve return an valid libmkkernel::MK_BUS 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_BUS is returned than the netHdl is valid.

MkBufferStreamGetNull()

static MK_BUS libmkkernel::MkBufferStreamGetNull ( void )

inlinestatic

Null-Slot - return a MkBufferStreamC typed NULL instance …

Definition at line 7835 of file LibMkKernel_mk.h.

                                                  {
    return (MK_BUS)MK_NULL;
  }

Here is the caller graph for this function:

MkBufferStreamHandleGet_RT()

static MK_HDL libmkkernel::MkBufferStreamHandleGet_RT ( MK_RT mkrt, MK_BUS const bus )

inlinestatic

Handle-Get-Slot - returns a export-hdl to the MkBufferStreamC 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 MkBufferStreamHandleResolve.

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]	bus	the MkBufferStreamS instance to work on

Returns

the required export-hdl

Definition at line 7777 of file LibMkKernel_mk.h.

  {
  return MkObjectHandleGet(bus?MkOBJ(bus):NULL);
}

Here is the caller graph for this function:

MkBufferStreamHandleResolve_RT()

static MK_BUS libmkkernel::MkBufferStreamHandleResolve_RT ( MK_RT mkrt, MK_HDL const netHdl )

inlinestatic

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

The MkBufferStreamHandleResolve undo the MkBufferStreamHandleGet 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 MkBufferStreamHandleGet

Returns

the required handle or MK_NULL if netHdl is invalid

Definition at line 7794 of file LibMkKernel_mk.h.

  {
  return MkBus(MkObjectHandleResolve(netHdl));

MkBufferStreamInstances_RT()

static MK_BUS libmkkernel::MkBufferStreamInstances_RT ( MK_RT mkrt )

inlinestatic

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

The head-instance is the last instance created.
