ftp_nb_fget

说明

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

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

参数

返回值

Returns FTP_FAILED or FTP_FINISHED or FTP_MOREDATA.
