[Vortex] vortex_hash_clear

Hash: SHA384

Hi, I use vortex_hash in one of my modules and want to delete every  
key/value pair by calling a value-destroy method in a way that the hash  
survives and can be re-used.

"vortex_hash_clear" documentation is a but unclear if entries will only be  
removed from the hash, or if registred destroy methods will be called too.

Even not explicitly stated I assume that "vortex_hash_destroy" makes the  
hash-table no longer valid, so no re-using possible.

What's the best way to delete all elements from the hash without having to  
give the KEYs?
