PRUint32 writeFrom ( nsIInputStream inStr , PRUint32 count )

Implementer's note: This method is defined by this interface in order to allow the output stream to efficiently copy the data from the input stream into its internal buffer (if any). If this method was provide as an external facility, a separate char* buffer would need to be used in order to call the output stream's other Write method.
