Definition and Usage

The ftp_nb_continue() function continues to receive/send a file to the FTP server.

This function returns one of the following values:

  • FTP_FAILED (send/receive failed)
  • FTP_FINISHED (send/receive completed)
  • FTP_MOREDATA (send/receive in progress)

This function sends/retrieves the file asynchronously. This means your program can perform other operations while the file is being downloaded.
