If 'Dir' is thread-safe (because of using TLS memory), mutex usage is useless whatever the instruction sequence calling 'Dir'.

Can you expand a bit?

It does not surprise me that 'Dir' is not thread safe. To get a list of items in a directory, 'Dir' must be called multiple times (because returning only one item per call) in a section of code (multiple lines of code). So to avoid any conflict with another thread using 'Dir'...

Warning when using dynamic instances of ThreadInitThenMultiStart or ThreadPooling When using dynamic instances of these types, their addresses should not be changed during their lifetimes, due to the associated internal thread that constantly accesses the data members from a pointer passed once to ...

In the 'Syntax' paragraph of the documentation pages, one or more declaration syntaxes are listed for information only. As many keywords support alternative syntaxes with parameters of different types, these declaration syntaxes are just synthetic images of the internal compiler declarations. These ...

The initializer '= Any' should be reserved for very specific cases where the gain of a few microseconds is necessary. Otherwise, beware of crashes if this is applied to UDTs containing member objects that must absolutely be initialized at least by default (already the var-len strings or dyna...

is redim inside threads safe? If the critical section of the code accessing the array (Redim, read/write access, access to U/Lbound, ...) in each thread code including the main code (implicit thread) is protected by a locking/unlocking mutex block, this mutex being common to all threads (including ...

A little short to fully understand your thread management principle.
(sample code would be welcome)

The many variables can be grouped together in structure(s) such as UDT(s). Therefore, only UDT instance(s) is(are) passed as parameter(s).

A problem with your PC(s) ?

Could we have some news?

T I have separate subs and functions and global variables with global structures working as 1 BIG file but would link to know what to do to have them as separate modules in separate files. Already, it is not good to use global variables in a module to pass them implicitly to internal procedures, in...

KeyPgPtr → fxm [this modifier can also be applied to UDTs]

I have some errors with 1.07.3 ( but OK with 1.07.1 ) That would surprise me a lot! I think the "Define" is rather intended to be used as this (if there is a function returning it): #define ZSTD_COMPRESSBOUND(srcSize) (((srcSize) + ((srcSize) shr 8)) + iif((srcSize) < (128 shl 10), ((128 ...

is any way here, to get the count of virtual functions, in runtime? To my knowledge no. I think the compiler fills in a new vtable for each new class (type with virtual procedures) on the fly, but probably Jeff or dkl can answer better than me. Everything I know about the vptr / vtable structure is...
