read_ftp
read_ftp, site, files, dir, port, data=data, file=file, user=user, pass=pass, ptr=ptr
Parameters
site
files
A single filename or an array of filenames to be retrieved.
dir
Remote directory where the files reside on the ftp server
port
Keywords
data
Set this to a named variable that will contain either a
byte array or an array of pointers to byte arrays with the
transferred data. If there is more than one file, an array
of pointers is returned, one for each file.
Note that when downloading large files using /FILE
instead will require much less memory since the entire file
is not stored in a variable in that case.
file
Set this keyword to make a local copy of the file to be
transferred. The local file will have the same name as the
remote file and will be placed in the current working
directory.
user
Specify user name to connect to server with.
pass
Specify password to use when connecting.
ptr
Set this keyword to return an array of pointers
even when there is only one file.
