Parameters
This Pointer to the EFI_PXE_BASE_CODE instance.
Operation The type of operation to perform. See “Related Definitions” below for
the list of operation types.
BufferPtr A pointer to the data buffer. Ignored for read file if DontUseBuffer
is TRUE .
Overwrite Only used on write file operations. TRUE if a file on a remote server can
be overwritten.
BufferSize For get-file-size operations, *BufferSize returns the size of the
requested file. For read-file and write-file operations, this parameter is
set to the size of the buffer specified by the
BufferPtr parameter. For
read-file operations, if EFI_BUFFER_TOO_SMALL is returned,
*BufferSize returns the size of the requested file.
BlockSize The requested block size to be used during a TFTP transfer. This must
be at least 512. If this field is
NULL , then the largest block size
supported by the implementation will be used.
ServerIp The TFTP / MTFTP server IP address.
Filename A Null-terminated ASCII string that specifies a directory name or a file
name. This is ignored by MTFTP read directory.
