# ftp_nb_fget

(PHP 4 >= 4.3.0)

ftp_nb_fget -- Retrieves a file from the FTP server and writes it to an open file (non-blocking)

## Description

int ftp_nb_fget ( resource ftp_stream, resource handle, string remote_file, int mode [, int resumepos])

ftp_nb_fget() retrieves `remote_file` from the FTP server, and writes it to the given file pointer, `handle`. The transfer `mode` specified must be either `FTP_ASCII` or `FTP_BINARY`. The difference between this function and the ftp_fget() is that this function retrieves the file asynchronously, so your program can perform other operations while the file is being downloaded.

Returns `FTP_FAILED`, `FTP_FINISHED`, or `FTP_MOREDATA`.
