int DWC_GetGHTTPDataEx(
const char* url,
int bufferlen,
BOOL buffer_clear,
DWCGHTTPProgressCallback progressCallback,
DWCGHTTPCompletedCallback completedCallback,
void* param );
Downloads data from the URL specified with url.
When post has been specified as NULL, this function behaves identically to DWC_GetGHTTPDataEx2.
If the DWC_ProcessGHTTP function is called repeatedly after calling this function, the communication process will proceed and the completion callback will be called when the process completes.
To find the communication status during processing, call the DWC_GetGHTTPState function using the request identifier of the return value.
