The tftpc_fwrite function writes a block of data to the local file identified by the file stream pointer. The argument buf points to the buffer containing the data that is to be written to the file. The argument len specifies the number of bytes to write to the file.

The tftpc_fwrite function is in the TFTPC_uif.c module. The prototype is defined in net_config.h.

note

• The tftpc_fwrite function must write len bytes. The TFTP Client stops writing and closes the TFTP session, if the return value is less than len bytes.
• This is an interface function of TFTP Client.

The tftpc_fwrite function returns the number of bytes written to the file.

  /* Write data to file. Return number of bytes actually written. */
