 Get the reference counter of this object.
 
void IncrementRefCounter () noexcept
 Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
 
int DecrementRefCounter () noexcept
 Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
 
virtual void Delete () const
 Memory deallocator for transient classes.

Constructor & Destructor Documentation

◆ Resource_Manager() [1/3]

Resource_Manager::Resource_Manager ( const char *const aName,
const bool Verbose = false )

Create a Resource manager. Attempts to find the two following files: $CSF_aNameDefaults/aName $CSF_aNameUserDefaults/aName and load them respectively into a reference and a user resource structure.

If CSF_ResourceVerbose defined, seeked files will be printed.

FILE SYNTAX The syntax of a resource file is a sequence of resource lines terminated by newline characters or end of file. The syntax of an individual resource line is:
