Function cuda_free_locked 

pub unsafe fn cuda_free_locked<T>(ptr: *mut T) -> CudaResult<()>

Free page-locked memory allocated with cuda_malloc_host.

Errors

If freeing memory fails, returns the CUDA error value. If the given pointer is null, returns InvalidValue.

Safety

The given pointer must have been allocated with cuda_malloc_locked, or null. The caller is responsible for ensuring that no other pointers to the deallocated buffer exist.

Examples

use rustacuda::memory::*;
unsafe {
    let locked_buffer = cuda_malloc_locked::<u64>(5).unwrap();
    // Free allocated memory
    cuda_free_locked(locked_buffer).unwrap();
}
