21   DevicePath including the end of device path node.  If DevicePath is NULL, then 0 is returned.

31   IN CONST EFI_DEVICE_PATH_PROTOCOL  *DevicePath
34   return GetDevicePathSize (DevicePath);
41   This function allocates space for a new copy of the device path specified by DevicePath.  If
42   DevicePath is NULL, then NULL is returned.  If the memory is successfully allocated, then the
43   contents of DevicePath are copied to the newly allocated buffer, and a pointer to that buffer
46   @param  DevicePath                 A pointer to a device path data structure.

94   DevicePathNode to a copy of the device path specified by DevicePath in an allocated buffer.
96   If DevicePathNode is NULL then a copy of DevicePath is returned.
97   If DevicePath is NULL then a copy of DevicePathNode, followed by an end-of-device path device
99   If both DevicePathNode and DevicePath are NULL then a copy of an end-of-device-path device node
105   @param  DevicePath                 A pointer to a device path data structure.

126   by DevicePathInstance to a copy of the device path specified by DevicePath in a allocated buffer.
129   If DevicePath is NULL, then a copy if DevicePathInstance is returned.
135   @param  DevicePath                 A pointer to a device path data structure.
144   IN CONST EFI_DEVICE_PATH_PROTOCOL *DevicePath,
148   return AppendDevicePathInstance (DevicePath, DevicePathInstance);
155   This function creates a copy of the current device path instance. It also updates DevicePath to
158   If DevicePath is NULL, then NULL is returned.
164   @param  DevicePath                 On input, this holds the pointer to the current device path

182   return GetNextDevicePathInstance (DevicePath, Size);
188   This function returns TRUE if the device path specified by DevicePath is multi-instance.
189   Otherwise, FALSE is returned.  If DevicePath is NULL, then FALSE is returned.
191   @param  DevicePath                 A pointer to a device path data structure.
193   @retval  TRUE                      DevicePath is multi-instance.
