wodSFTP API library - GetFiles Method
      
 

Description

Downloads multiple files in a sequence, recursive.


Return type

A Long value. If successful, 0 is returned, otherwise error as specified here.


Syntax

long Sftp_GetFiles(void *Sftp, char *LocalPath, char * RemotePath, int MaxLevel);

The GetFiles function syntax has these parts:

Part Description
void *Sftp Handle of the created Sftp instance.
char *LocalPath Holds full path on local disk where files are downloaded.
char *RemotePath Holds full path on the server from where files are downloaded.
int MaxLevel Specifies maximum number of subdirectory levels to copy. 0 for unlimited.

Remarks

This function will try to download complete directory structure of the server to local disk. You need to specify LocalPath argument that points to a directory where files are placed, and RemotePath that determines location from where are files copied.

GetFiles will go and recursive copy directories and files - corresponding directory structure will also be created on local disk. If remote item that is copied is a symbolic link, it is resolved to appropriate file/folder whose contents are also copied.

wodSFTP will go up to MaxLevel deep into recursion. Default value is 5 - meaning up to 5 subdirectory levels will be copied. You can specify any value for MaxLevel. If you specify 0, that means that no restriction exists for recursion depth - this is dangerous setting that could cause infinite loops to be created if remote system has symbolic links pointing back to other items that is already copied!

Before each item is copied, LoopItem callback will be called, specifying local name of the file/folder, its remote name (including full path in both cases), type of the item (file/folder/symbolic link) and will allow you to Skip the item so it is not copied locally at all. Make sure your logic for setting Skip = True is correct - if you skip creation of local directory and then try to download files to it, you may get more errors! Since GetFiles does not support wildcards (for example, you cannot specify "*.TXT" in GetFiles call), LoopItem is a place to determine if certain item matches your wildcard expression (if you have any), so you can skip files that doesn't match your criteria.

If an errors occurs during file download, LoopError callback is called holding error number and error description of the error. If you leave ErrorCode argument in LoopError callback as is - GetFiles operation will be aborted. If you change ErrorCode value in LoopError event to 0, then GetFiles operation will continue (ignoring the error) normally.

Do not forget that RemotePath should always specify full absolute path (i.e. /home/joe/something) instead of relative path (i.e. joe/something). LocalPath should also specify full path (i.e. C:\home\joe\something) instead of relative path (i.e. joe\something).
