bool Readline::PromptEOF ( std::string &  str )

virtual

This function is a wrapper around the call to readline. It encapsultes the return buffer into a std::string and deletes the memory allocated by readline. Furthermore, it removes leading and trailing whitespaces before return the result. The result is returned in the given argument containing the prompt. Before the function returns Shutdown() is called (as opposed to Startup when readline starts)

Parameters

str	The prompt which is to be shown by the readline libarary. it is directly given to the call to readline. The result of the readline call is returned in this string.

Returns

true if the call succeeded as usual, false if EOF was detected by the readline call.
