wrapper for MkBufferHandleResolve with error-handline

Parameters

[in]

netHdl

The handle previously returned by MkObjectHandleGet.

Returns

Return an valid libmkkernel::MK_BUF 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.
• MkBufferHandleResolve return an valid libmkkernel::MK_BUF 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_BUF is returned than the netHdl is valid.

Function Documentation

MkBufferGetNull()

MK_BUF libmkkernel::MkBufferGetNull ( void )

inline

Null-Slot - return a MkBufferC typed NULL instance …

Definition at line 5448 of file LibMkKernel_mk.h.

                                            {
    return (MK_BUF)MK_NULL;
  }

Here is the caller graph for this function:

MkBufferHandleGet_RT()

MK_HDL libmkkernel::MkBufferHandleGet_RT ( MK_RT const mkrt, MK_BUF const buf )

inline

Handle-Get-Slot - returns a export-hdl to the MkBufferC 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 MkBufferHandleResolve.

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]	buf	the MkBufferS instance to work on

Returns

the required export-hdl

Definition at line 5391 of file LibMkKernel_mk.h.

MkBufferHandleResolve_RT()

MK_RT_ATTR_HDL MK_BUF libmkkernel::MkBufferHandleResolve_RT ( MK_RT const mkrt, MK_HDL const netHdl )

inline

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

The MkBufferHandleResolve undo the MkBufferHandleGet 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 MkBufferHandleGet

Returns

the required handle or MK_NULL if netHdl is invalid

  {
  return MkBuf(MkObjectHandleResolve(netHdl));
} MK_RT_ATTR_RUNTIME

MkBufferInstances_RT()

MK_BUF libmkkernel::MkBufferInstances_RT ( MK_RT_PARSER_ONLY )

inline

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

The head-instance is the last instance created.
