6.23 acc_delete – Free device memory. ¶

Description

This function frees previously allocated device memory specified by the device address a and the length of len bytes.

In Fortran, two (2) forms are supported. In the first form, a specifies a contiguous array section. The second form a specifies a variable or array element and len specifies the length in bytes.

C/C++:

Prototype:	acc_delete(h_void *a, size_t len);
Prototype:	acc_delete_async(h_void *a, size_t len, int async);
Prototype:	acc_delete_finalize(h_void *a, size_t len);
Prototype:	acc_delete_finalize_async(h_void *a, size_t len, int async);

Fortran:

Interface:	subroutine acc_delete(a)
	type, dimension(:[,:]...) :: a
Interface:	subroutine acc_delete(a, len)
	type, dimension(:[,:]...) :: a
	integer len
Interface:	subroutine acc_delete_async(a, async)
	type, dimension(:[,:]...) :: a
	integer(acc_handle_kind) :: async
Interface:	subroutine acc_delete_async(a, len, async)
	type, dimension(:[,:]...) :: a
	integer len
	integer(acc_handle_kind) :: async
Interface:	subroutine acc_delete_finalize(a)
	type, dimension(:[,:]...) :: a
Interface:	subroutine acc_delete_finalize(a, len)
	type, dimension(:[,:]...) :: a
	integer len
Interface:	subroutine acc_delete_async_finalize(a, async)
	type, dimension(:[,:]...) :: a
	integer(acc_handle_kind) :: async
Interface:	subroutine acc_delete_async_finalize(a, len, async)
	type, dimension(:[,:]...) :: a
	integer len
	integer(acc_handle_kind) :: async
