#define MID_HADOOPDFS_LISTRESOURCES 12

IPWORKSCLOUD_EXTERNAL int IPWORKSCLOUD_CALL IPWorksCloud_HadoopDFS_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

This method lists resources within the directory at DirPath.

Calling this method will fire the ResourceList event once for each resource, and will also populate the Resource* properties.

DirPath may be empty to list resources in the root directory (/).

// ResourceList event handler.
hdfs.OnResourceList += (s, e) => {
  Console.WriteLine(e.Name);
};

hdfs.ListResources("/work_files/serious_business/cats");

for (int i = 0; i < hdfs.Resources.Count; i++) {
  // Process resources here.
}

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
