Typedef Documentation

EFI_DEVICE_PATH_TO_TEXT_NODE

typedef CHAR16 *(EFIAPI * EFI_DEVICE_PATH_TO_TEXT_NODE) (IN CONST EFI_DEVICE_PATH_PROTOCOL *DeviceNode, IN BOOLEAN DisplayOnly, IN BOOLEAN AllowShortcuts)

Convert a device node to its text representation.

Parameters

DeviceNode	Points to the device node to be converted.
DisplayOnly	If DisplayOnly is TRUE, then the shorter text representation of the display node is used, where applicable. If DisplayOnly is FALSE, then the longer text representation of the display node is used.
AllowShortcuts	If AllowShortcuts is TRUE, then the shortcut forms of text representation for a device node can be used, where applicable.

Return values

a_pointer	a pointer to the allocated text representation of the device node data
NULL	if DeviceNode is NULL or there was insufficient memory.

EFI_DEVICE_PATH_TO_TEXT_PATH

typedef CHAR16 *(EFIAPI * EFI_DEVICE_PATH_TO_TEXT_PATH) (IN CONST EFI_DEVICE_PATH_PROTOCOL *DevicePath, IN BOOLEAN DisplayOnly, IN BOOLEAN AllowShortcuts)

Convert a device path to its text representation.

Parameters

DevicePath	Points to the device path to be converted.
DisplayOnly	If DisplayOnly is TRUE, then the shorter text representation of the display node is used, where applicable. If DisplayOnly is FALSE, then the longer text representation of the display node is used.
AllowShortcuts	The AllowShortcuts is FALSE, then the shortcut forms of text representation for a device node cannot be used.

Return values

a_pointer	a pointer to the allocated text representation of the device node.
NULL	if DevicePath is NULL or there was insufficient memory.
