Syntax

ANSI (Cross Platform)
int GetFeed(const char* lpszURL);

Unicode (Windows)
INT GetFeed(LPCWSTR lpszURL);

- (void)getFeed:(NSString*)URL;

#define MID_RSS_GETFEED 7

IPWORKS_EXTERNAL int IPWORKS_CALL IPWorks_RSS_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

This method fetches documents using the HTTP GET method. The document contents are delivered in the RSSData property, as well as through the Transfer event, and the HTTP response headers through the Header event. If the LocalFile property has been set, the class will write the transferred data there.

The class will then attempt to parse the RSS feed, filling in the Channel and Item properties as it goes. The feed properties can be accessed either directly through the named properties, or through the GetProperty and SetProperty methods.

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.)
