Function Documentation

DevicePathToStr()

CHAR16 *EFIAPI DevicePathToStr

(

IN EFI_DEVICE_PATH_PROTOCOL *

DevPath

)

This function converts an input device structure to a Unicode string.

Parameters

[in]

DevPath

A pointer to the device path structure.

Returns

A new allocated Unicode string that represents the device path.

Definition at line 131 of file WifiConnectionMgrFileUtil.c.

ExtractFileNameFromDevicePath()

CHAR16 * ExtractFileNameFromDevicePath

(

IN EFI_DEVICE_PATH_PROTOCOL *

DevicePath

)

Extract filename from device path. The returned buffer is allocated using AllocateCopyPool. The caller is responsible for freeing the allocated buffer using FreePool(). If return NULL means not enough memory resource.

Parameters

DevicePath

Device path.

Return values

NULL	Not enough memory resourece for AllocateCopyPool.
Other	A new allocated string that represents the file name.

IsDerPemEncodeCertificate()

BOOLEAN IsDerPemEncodeCertificate

(

IN CONST CHAR16 *

FileSuffix

)

This code checks if the FileSuffix is one of the possible DER/PEM-encoded certificate suffix.

Parameters

[in]

FileSuffix

The suffix of the input certificate file

Return values

TRUE	It's a DER/PEM-encoded certificate.
FALSE	It's NOT a DER/PEM-encoded certificate.

ReadFileContent()

EFI_STATUS ReadFileContent	(	IN EFI_FILE_HANDLE	FileHandle,
		IN OUT VOID **	BufferPtr,
		OUT UINTN *	FileSize,
		IN UINTN	AddtionAllocateSize
	)

Read file content into BufferPtr, the size of the allocate buffer is *FileSize plus AddtionAllocateSize.

Parameters

[in]	FileHandle	The file to be read.
[in,out]	BufferPtr	Pointers to the pointer of allocated buffer.
[out]	FileSize	Size of input file
[in]	AddtionAllocateSize	Addtion size the buffer need to be allocated. In case the buffer need to contain others besides the file content.

Return values

EFI_SUCCESS	The file was read into the buffer.
EFI_INVALID_PARAMETER	A parameter was invalid.
EFI_OUT_OF_RESOURCES	A memory allocation failed.
others	Unexpected error.

Parameters

[in]	Private	The pointer to the global private data structure.
[in]	FilePath	Point to the file path.

Return values

TRUE	Exit caller function.
FALSE	Not exit caller function.

UpdatePage()

BOOLEAN UpdatePage	(	IN WIFI_MGR_PRIVATE_DATA *	Private,
		IN EFI_DEVICE_PATH_PROTOCOL *	FilePath,
		IN EFI_FORM_ID	FormId
	)

Update the form base on the selected file.

Parameters

[in]	Private	The pointer to the global private data structure.
[in]	FilePath	Point to the file path.
[in]	FormId	The form needs to display.

Return values

TRUE	Exit caller function.
FALSE	Not exit caller function.

Definition at line 203 of file WifiConnectionMgrFileUtil.c.

UpdatePrivateKeyFromFile()

BOOLEAN UpdatePrivateKeyFromFile	(	IN WIFI_MGR_PRIVATE_DATA *	Private,
		IN EFI_DEVICE_PATH_PROTOCOL *	FilePath
	)

Update the Private Key form base on the input file path info.

Parameters

[in]	Private	The pointer to the global private data structure.
[in]	FilePath	Point to the file path.

Return values

TRUE	Exit caller function.
