Parameters
This Pointer to the EFI_PXE_BASE_CODE instance.
Operation The type of operation to perform. See "Related Definitions" 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 read-file and write-file operations, this is the size of the buffer
specified by BufferPtr. For read file operations, if BufferSize is
smaller than the size of the file being read, then this field will return the
required size. For get-file size operations, this field 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.
