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.
