Function: release_mem_address

C Prototype	aclError *aclrtReleaseMemAddress(void virPtr)**
Python Function	ret = acl.rt.release_mem_address(vir_ptr)
Function Usage	Frees the virtual memory allocated by the acl.rt.reserve_mem_address call. This API needs to work with other APIs to allocate virtual memory with consecutive addresses and maximize the use of physical memory. Call acl.rt.reserve_mem_address to allocate virtual memory. Call acl.rt.malloc_physical to allocate physical memory. Call acl.rt.map_mem to map the virtual memory to the physical memory. Call specific task APIs to execute tasks. Call acl.rt.unmap_mem to unmap the virtual memory from the physical memory. Call acl.rt.free_physical to free the physical memory. Call acl.rt.release_mem_address to free the virtual memory.
Input Description	vir_ptr: int, pointing to the address of the virtual address space to be released.
Return Value	ret: int, error code. 0 indicates success. Other values indicate failure.
Restrictions	This API is not supported in Ascend RC form. If the virtual memory is mapped to physical memory, you need to unmap them by calling acl.rt.unmap_mem before freeing the virtual memory.
