tftpc_put

#include <rtl.h>

BOOL tftpc_put (
    U8*   ipadr,                   /* IP address of the TFTP server. */
    U16   port,                    /* Port number of TFTP server. */
    const char *src,               /* Name of the local file to send. */
    const char *dst,               /* Name of the file on TFTP server. */
    void (*cbfunc)(U8 event) );    /* Function to call when the session ends. */

The tftpc_put function starts the TFTP client on the TCPnet system to transfer a file from the local system to remote TFTP server. This causes the TFTP client to then start a TFTP session by connecting to a TFTP server on the UDP port specified in the function argument. If the port is not specified, that is the argument port has a value of 0, the system uses a standard TFTP server port to connect to.

The argument ipadr points to an array of 4 bytes containing the dotted-decimal notation of the IP address of the TFTP server to connect to.

The arguments src and dst are pointers to 0-terminated names of source and destination files. Source file is a local file that is going to be sent. Destination file is a file on TFTP server, where the file content will be copied to. If the destination file is not specified, that is the argument dst has a value of NULL, then the name of the source file becomes also a name of the destination file.

The argument cbfunc points to a function that the TFTP client running on TCPnet calls when the TFTP session ends. The cbfunc is an event callback function that uses the event argument of the cbfunc function to signal one of the following TFTP events:

The tftpc_put function is in the RL-TCPnet library. The prototype is defined in rtl.h.

note

• The standard TFTP server port is UDP port 69.
• Your application, running on TCPnet, can call the tftpc_put function to send a file to a TFTP server.

The tftpc_put function returns __TRUE if the TFTP client has been successfully started. Otherwise it returns __FALSE.
