/** | |
Send a file to an MTFTPv6 server. May be unsupported in some implementations. | |
The WriteFile() function is used to initialize an uploading operation with the given option list | |
and optionally wait for completion. If one or more of the options is not supported by the server, the | |
unsupported options are ignored and a standard TFTP process starts instead. When the upload | |
process completes, whether successfully or not, Token.Event is signaled, and the EFI MTFTPv6 | |
Protocol driver updates Token.Status. | |
The caller can supply the data to be uploaded in the following two modes: | |
- Through the user-provided buffer | |
- Through a callback function | |
With the user-provided buffer, the Token.BufferSize field indicates the length of the buffer, | |
and the driver will upload the data in the buffer. With an EFI_MTFTP6_PACKET_NEEDED | |
callback function, the driver will call this callback function to get more data from the user to upload. | |
See the definition of EFI_MTFTP6_PACKET_NEEDED for more information. These two modes | |
cannot be used at the same time. The callback function will be ignored if the user provides the | |
buffer. | |

/** | |
Download a data file directory from an MTFTPv6 server. May be unsupported in some implementations. | |
The ReadDirectory() function is used to return a list of files on the MTFTPv6 server that are | |
logically (or operationally) related to Token.Filename. The directory request packet that is sent | |
to the server is built with the option list that was provided by caller, if present. | |
The file information that the server returns is put into either of the following locations: | |
- A fixed buffer that is pointed to by Token.Buffer | |
- A download service function that is pointed to by Token.CheckPacket | |
If both Token.Buffer and Token.CheckPacket are used, then Token.CheckPacket | |
will be called first. If the call is successful, the packet will be stored in Token.Buffer. | |
The returned directory listing in the Token.Buffer or EFI_MTFTP6_PACKET consists of a list | |
of two or three variable-length ASCII strings, each terminated by a null character, for each file in the | |
directory. If the multicast option is involved, the first field of each directory entry is the static | |
multicast IP address and UDP port number that is associated with the file name. The format of the | |
field is ip:ip:ip:ip:port. If the multicast option is not involved, this field and its terminating | |
null character are not present. | |
The next field of each directory entry is the file name and the last field is the file information string. | |
The information string contains the file size and the create/modify timestamp. The format of the | |
information string is filesize yyyy-mm-dd hh:mm:ss:ffff. The timestamp is | |
Coordinated Universal Time (UTC; also known as Greenwich Mean Time [GMT]). | |

Polls for incoming data packets and processes outgoing data packets. | |
The Poll() function can be used by network drivers and applications to increase the rate that data | |
packets are moved between the communications device and the transmit and receive queues. | |
In some systems, the periodic timer event in the managed network driver may not poll the | |
underlying communications device fast enough to transmit and/or receive all data packets without | |
missing incoming packets or dropping outgoing packets. Drivers and applications that are | |
experiencing packet loss should try calling the Poll() function more often. | |
