Function Documentation

MkLogFileClose_RT()

void libmkkernel::MkLogFileClose_RT	(	MK_RT	mkrt,
		MK_LFL	lfh )

Destructor - delete a MkLogFileC instance …

There are two different ways to delete an instance:

ObjectDispose	to free the internal data but keep the outher shell alive - this is called a SOFT-DELETE
ObjectDelete	to delete the outher shell including the internal data - this is called a HARD-DELETE

Attention

1. The internal memory will be freed and the object-pointer will be set to NULL. If the object-pointer is already NULL nothing will be done.
2. For a programming language without HARD-Delete support, the "Delete" method is assigned to a SOFT-Delete.
3. For a programming language without garbage collection, a SOFT-delete without a HARD-delete causes a small memory loss (C++: ~32 bytes).
4. After a SOFT-delete, the outher shell is still alive, but cannot be used. Any access to this shell generates an HDL-null-exception, but this exception can be caught. This is important for C++ as it prevents a core dump.
5. On HARD-delete read more at MkSelfDeleteForce

LogFileOpen

MkLogFileOpen_RT()

enum MkErrorE libmkkernel::MkLogFileOpen_RT	(	MK_RT	mkrt,
		MK_OBJN	fmtobj,
		MK_STRN const	file,
		MK_LFL *	lfh_out )

open the log-file in append mode …

The new instance belongs to the caller and may have to be released if necessary. A manual release using LogFileClose is always possible, but the instance can no longer be used afterwards.

Parameters

[in]	mkrt	the MkRuntimeS instance to work on - the runtime argument, used by MK_RT_CALL (C-only)
[in]	fmtobj	managed object used to format the log-message (default=MK_NULL → use default-format)
[in]	file	the filename to open
[out]	lfh_out	returns

Returns

The newly created MkLogFileC instance, the instance is owned by the caller

Exceptions

MkExceptionC

→ The default-exception from the Programming-Language-Micro-Kernel (PLMK)

Attention

on error the lfh_out is set to MK_NULL
