Summary

Functions

Test if a protocol is installed at a handle.

bool lv_uefi_protocol_test(EFI_HANDLE handle, EFI_GUID *protocol)

Name	Type	Description
`handle`	`EFI_HANDLE`	The handle on which the protocol might be installed.
`protocol`	`EFI_GUID *`	The guid of the protocol.

Returns: bool — TRUE if the protocol is installed, FALSE if not.

Open a protocol.

void * lv_uefi_protocol_open(EFI_HANDLE handle, EFI_GUID *protocol)

Name	Type	Description
`handle`	`EFI_HANDLE`	The handle on which the protocol is installed.
`protocol`	`EFI_GUID *`	The guid of the protocol.

Returns: void * — A pointer to the interface, NULL if the protocol couldn't be opened.

Close a protocol.

void lv_uefi_protocol_close(EFI_HANDLE handle, EFI_GUID *protocol)

Name	Type	Description
`handle`	`EFI_HANDLE`	The handle on which the protocol is installed.
`protocol`	`EFI_GUID *`	The guid of the protocol.

Convert an UCS-2 string to an ASCII string. The string must contain only characters >= 0x20 and <= 0X7E.

size_t lv_uefi_ucs2_to_ascii(const CHAR16 *ucs2, char *ascii, size_t ascii_len)

Name	Type	Description
`ucs2`	`const CHAR16 *`	The UCS-2 string.
`ascii`	`char *`	The buffer to store the ASCII string.
`ascii_len`	`size_t`	The size of the buffer in ASCII characters.

Returns: size_t — The number of characters written to the buffer or 0 if there was an error.

Convert an ASCII string to an UCS-2 string. The string must contain only characters >= 0x20 and <= 0X7E.

size_t lv_uefi_ascii_to_ucs2(const char *ascii, CHAR16 *ucs2, size_t ucs2_len)

Name	Type	Description
`ascii`	`const char *`	The ASCII string.
`ucs2`	`CHAR16 *`	The buffer to store the UCS-2 string.
`ucs2_len`	`size_t`	The size of the buffer in UCS-2 characters.
