Function cuda_free_locked

crates/cust/src/memory/malloc.rs:282–289

Free page-locked memory allocated with [`cuda_malloc_host`](fn.cuda_malloc_host.html). # 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. # Example

(ptr: *mut T)

/// }
/// ```
pub unsafe fn cuda_free_locked<T>(ptr: *mut T) -> CudaResult<()> {
    if ptr.is_null() {
        return Err(CudaError::InvalidMemoryAllocation);
    }

    cuda::cuMemFreeHost(ptr as *mut c_void).to_result()?;
    Ok(())
