FTP_NB_FGET(3)								 1							    FTP_NB_FGET(3)

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

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

DESCRIPTION
       ftp_nb_fget(3) retrieves a remote file from the FTP server.

	The  difference between this function and ftp_fget(3) is that this function retrieves the file asynchronously, so your program can perform
       other operations while the file is being downloaded.

	      o $ftp_stream
		- The link identifier of the FTP connection.

	      o $handle
		- An open file pointer in which we store the data.

	      o $remote_file
		- The remote file path.

	      o $mode
		- The transfer mode. Must be either FTP_ASCII or FTP_BINARY.

	      o $resumepos
		-The position in the remote file to start downloading from.

RETURN VALUES
