Return Memory to omp_alloc

Deprecated 2011-08-31
Use the function thread_alloc::return_memory instead.

Syntax
# include <cppad/utility/omp_alloc.hpp>
 omp_alloc::return_memory(v_ptr)

Purpose
If omp_max_num_threads is one, the memory is returned to the system. Otherwise, the memory is retained by omp_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 omp_get_memory and not yet returned.

Thread
Either the current thread must be the same as during the corresponding call to omp_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.
