Here is a link to its current documentation . Return Memory to thread_alloc
Syntax
thread_alloc::return_memory(v_ptr)

Purpose
If hold_memory is false, the memory is returned to the system. Otherwise, the memory is retained by thread_alloc for quick future use by the thread that allocated to memory.

v_ptr
This argument has prototype
    void* v_ptr
. It must be a pointer to memory that is currently in use; i.e. obtained by a previous call to get_memory and not yet returned.

Thread
Either the current thread must be the same as during the corresponding call to get_memory , or the current execution mode must be sequential (not parallel ).

NDEBUG
If NDEBUG is defined, v_ptr is not checked (this is faster). Otherwise, a list of in use pointers is searched to make sure that v_ptr is in the list.

Example
thread_alloc.cpp
