/**
|

Reads the requested number of blocks from the specified block device.
|
||||
|
||||
The function reads the requested number of blocks from the device. All the
|
||||
blocks are read, or an error is returned. If there is no media in the device,
|
||||
the function returns EFI_NO_MEDIA.
|
||||
|
||||
@param[in] PeiServices General-purpose services that are available to
|
||||
every PEIM.
|
||||
@param[in] This Indicates the EFI_PEI_RECOVERY_BLOCK_IO2_PPI instance.
|
||||
@param[in] DeviceIndex Specifies the block device to which the function wants
|
||||
to talk. Because the driver that implements Block I/O
|
||||
PPIs will manage multiple block devices, PPIs that
|
||||
want to talk to a single device must specify the device
|
||||
index that was assigned during the enumeration process.
|
||||
This index is a number from one to NumberBlockDevices.
|
||||
@param[in] StartLBA The starting logical block address (LBA) to read from
|
||||
on the device
|
||||
@param[in] BufferSize The size of the Buffer in bytes. This number must be
|
||||
a multiple of the intrinsic block size of the device.
|
||||
@param[out] Buffer A pointer to the destination buffer for the data.
|
||||
The caller is responsible for the ownership of the
|
||||
buffer.
|
||||
|
||||
@retval EFI_SUCCESS The data was read correctly from the device.
|
||||
@retval EFI_DEVICE_ERROR The device reported an error while attempting
|
||||
to perform the read operation.
|
||||
@retval EFI_INVALID_PARAMETER The read request contains LBAs that are not
|
||||
valid, or the buffer is not properly aligned.
|
||||
@retval EFI_NO_MEDIA There is no media in the device.
|
||||
@retval EFI_BAD_BUFFER_SIZE The BufferSize parameter is not a multiple of
|
||||
the intrinsic block size of the device.
