Detailed Description

The UEFI Library provides functions and macros that simplify the development of UEFI Drivers and UEFI Applications. These functions and macros help manage EFI events, build simple locks utilizing EFI Task Priority Levels (TPLs), install EFI Driver Model related protocols, manage Unicode string tables for UEFI Drivers, and print messages on the console output and standard error devices.

GetEfiGlobalVariable2()

EFI_STATUS EFIAPI GetEfiGlobalVariable2	(	IN CONST CHAR16 *	Name,
		OUT VOID **	Value,
		OUT UINTN *Size	OPTIONAL
	)

Returns a pointer to an allocated buffer that contains the contents of a variable retrieved through the UEFI Runtime Service GetVariable(). This function always uses the EFI_GLOBAL_VARIABLE GUID to retrieve variables. The returned buffer is allocated using AllocatePool(). The caller is responsible for freeing this buffer with FreePool().

If Name is NULL, then ASSERT(). If Value is NULL, then ASSERT().

Parameters

[in]	Name	The pointer to a Null-terminated Unicode string.
[out]	Value	The buffer point saved the variable info.
[out]	Size	The buffer size of the variable.

Returns

EFI_OUT_OF_RESOURCES Allocate buffer failed.

EFI_SUCCESS Find the specified variable.

Others Errors Return errors from call to gRT->GetVariable.

GetVariable2()

EFI_STATUS EFIAPI GetVariable2	(	IN CONST CHAR16 *	Name,
		IN CONST EFI_GUID *	Guid,
		OUT VOID **	Value,
		OUT UINTN *Size	OPTIONAL
	)

Returns the status whether get the variable success. The function retrieves variable through the UEFI Runtime Service GetVariable(). The returned buffer is allocated using AllocatePool(). The caller is responsible for freeing this buffer with FreePool().

If Name is NULL, then ASSERT(). If Guid is NULL, then ASSERT(). If Value is NULL, then ASSERT().

Parameters

[in]	Name	The pointer to a Null-terminated Unicode string.
[in]	Guid	The pointer to an EFI_GUID structure
[out]	Value	The buffer point saved the variable info.
[out]	Size	The buffer size of the variable.

Returns

EFI_OUT_OF_RESOURCES Allocate buffer failed.

EFI_SUCCESS Find the specified variable.

Others Errors Return errors from call to gRT->GetVariable.

GetVariable3()

EFI_STATUS EFIAPI GetVariable3	(	IN CONST CHAR16 *	Name,
		IN CONST EFI_GUID *	Guid,
		OUT VOID **	Value,
		OUT UINTN *Size	OPTIONAL,
		OUT UINT32 *Attr	OPTIONAL
	)

Return the attributes of the variable.

Returns the status whether get the variable success. The function retrieves variable through the UEFI Runtime Service GetVariable(). The returned buffer is allocated using AllocatePool(). The caller is responsible for freeing this buffer with FreePool(). The attributes are returned if the caller provides a valid Attribute parameter.

If Name is NULL, then ASSERT(). If Guid is NULL, then ASSERT(). If Value is NULL, then ASSERT().

Parameters

[in]	Name	The pointer to a Null-terminated Unicode string.
[in]	Guid	The pointer to an EFI_GUID structure
[out]	Value	The buffer point saved the variable info.
[out]	Size	The buffer size of the variable.
[out]	Attr	The pointer to the variable attributes as found in var store

Return values

EFI_OUT_OF_RESOURCES	Allocate buffer failed.
EFI_SUCCESS	Find the specified variable.
Others	Errors Return errors from call to gRT->GetVariable.
