255 This function allocates space for a new copy of the device path specified by DevicePath. If
256 DevicePath is NULL, then NULL is returned. If the memory is successfully allocated, then the
257 contents of DevicePath are copied to the newly allocated buffer, and a pointer to that buffer

308 DevicePathNode to a copy of the device path specified by DevicePath in an allocated buffer.
310 If DevicePathNode is NULL then a copy of DevicePath is returned.
311 If DevicePath is NULL then a copy of DevicePathNode, followed by an end-of-device path device
313 If both DevicePathNode and DevicePath are NULL then a copy of an end-of-device-path device node

341 by DevicePathInstance to a copy of the device path secified by DevicePath in a allocated buffer.
344 If DevicePath is NULL, then a copy if DevicePathInstance is returned.
346 If DevicePath or DevicePathInstance is invalid, then NULL is returned.

368 This function creates a copy of the current device path instance. It also updates DevicePath to
371 If DevicePath is NULL, then NULL is returned.
372 If DevicePath points to a invalid device path, then NULL is returned.
378 @param DevicePath On input, this holds the pointer to the current device path
384 bytes or zero, if DevicePath is NULL.
