omp_return_memory¶
View page sourceReturn 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.
