Synopsis #

Header: fxcg/serial.h
Syscall index: 0x13A6
Function signature: int App_LINK_TransmitInit(struct TransmitBuffer* txb)

Sends the transmit start packet for a file transfer using Protocol 7.00, and handles the file overwrite dialog in case the file already exists in the connected device. Before calling this syscall, preparation is necessary.

Parameters #

• txb - pointer to a struct like this (comments relative to the transfer of a file in storage memory):

  struct TTransmitBuffer {
      char device[0x008]; // fls0
      char directoryname[0x10A]; // can be an empty string, possibly controls in which folder the file goes on the destination device.
  // 0x112
      char fname1[0x10A]; // file name for the file on the destination device.
      char dummy[0x28];
      char fname2[0x00E];
  // 0x252
      unsigned short filename[0x10A]; // 16-bit string containing the full file name in the origin calculator, like this: \\fls0\ABC.G1A
  // 0x466
      char dummy2[0x1A];
  // 0x480
      int filesize; // the size, in bytes, of the file to send.
  // 0x484
      short dummy3;
  // 0x486
      char command; // set to 0x45
      char subcommand;
  // 0x488
      char datatype; // set to 0x80
      char dummy4_3;
      char dummy4_4;
      char dummy4_5;
  // 0x48C
      int handle; // initialize to -1
  // 0x490
      char dummy5[8];
  // 0x498
      char source; // set to 1
      char dummy6_1;
      char dummy6_2;
      char dummy6_3;
  // 0x49C
      int zero; // set to zero
  }
  

Returns #

0 on success, other values on error.

Comments #

After calling this syscall, App_LINK_Transmit can be used to proceed with the file transfer.
