FTPList (socket,list[,pathname,mode]) Returns status


Note: The flag is set according to whether Omnis was able to make a call to this external command.

This Web command is multi-threaded,allowing another thread to execute in the multi-threaded server while it runs. Note that the same socket cannot safely be used concurrently by more than one thread.

FTPList lists files on the FTP server.

Socket is an Omnis Long Integer field containing a socket opened to an FTP server using FTPConnect.

List is an Omnis List field containing a single column of type Character. This list receives the file listing information, one line per file, returned by the remote FTP server. The list is dependent on the type of the remote server and may be in long or short format, depending on the Mode parameter.

Note: Very often, FTP servers return long-format listings in a Linux file listing format. At a minimum, this file information contains the filename, but usually includes other information. The Omnis method must parse this information to find the filename and other information. For example

total 123          
drwxr-xr-x 4 userid mygroup Jan 1 1999 .
drwxr-xr-x 6 root root Jan 1 1999 ..
-rw------- 1 userid mygroup Jan 16 1998 myfile
-rw-r—r— 2 userid mygroup Jan 16 1998 myotherfile

Where the columns in the character string correspond to protection, file size, username and group of the file owner, the date last modified and the name of the file. The files "." and ".." represent the current and parent directories, respectively, which may neither be retrieved nor changed.

The file information may not be neatly spaced into columns as in this example. Columns are separated with one or more spacing characters (space, tab, and so on).

Pathname is an optional Omnis Character field that contains a pathname or wildcard specification for the files to include in the listing. If omitted, the default is to list all of the files in the current directory on the FTP server.

Mode is an optional numeric value which indicates whether the server should return a short or long format listing. If omitted, it defaults to zero.

Code Meaning
0 Filename-only listing
1 Long-format listing

Status is an Omnis Long Integer field which receives the result of executing the command. Possible error codes are listed in the Web Command Error Codes Appendix


Do iMyList.$define(iListColumn)
; return a long format listing of the current directory into the list variable iMyList
FTPList (iFTPSocket,iMyList,,1) Returns lErrCode
If lErrCode
  FTPGetLastStatus (iServerReplyText) Returns lErrCode
  OK message FTP Error {[con("Error obtaining list of files from the FTP server",kCr,"Details follow: ",kCr,iServerReplyText)]}
End If
