complete {RCurl}

Complete an asynchronous HTTP request

Description

This is a generic function that is used within the RCurl package to force the completion of an HTTP request. If the request is asynchronous, this essentially blocks until the request is completed by repeatedly asking for more information to be retrieved from the HTTP connection.

Usage

complete(obj, ...)

Arguments

obj

the object which is to be completed. This is typically a MultiCURLHandle-class instance.

...

additional arguments intended to be used by specific methods.

Value

The value is typically not of interest, but rather the side effect of processing the pending requests.
