wrapper for Sq3FileHandleResolve with error-handline

Parameters

[in]

netHdl

The handle previously returned by MkObjectHandleGet.

Returns

Return an valid libsq3lite::SQ3_FILE 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.
• Sq3FileHandleResolve return an valid libsq3lite::SQ3_FILE 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 libsq3lite::SQ3_FILE is returned than the netHdl is valid.

Here is the caller graph for this function:

Sq3FileHandleGet_RT()

static MK_HDL libsq3lite::Sq3FileHandleGet_RT ( MK_RT mkrt, SQ3_FILE const file )

inlinestatic

Handle-Get-Slot - returns a export-hdl to the Sq3FileC 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 Sq3FileHandleResolve.

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]	file	Programming-Language-Micro-Kernel (PLMK) instance from sqlite3_file

Returns

the required export-hdl

static SQ3_FILE libsq3lite::Sq3FileHandleResolve_RT ( MK_RT mkrt, MK_HDL const netHdl )

inlinestatic

Handle-Resolve-Slot - return a Sq3FileC from netHdl or MK_NULL if invalid…

The Sq3FileHandleResolve undo the Sq3FileHandleGet 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 Sq3FileHandleGet

Returns

the required handle or MK_NULL if netHdl is invalid
