set_input_string

Synopsis

#include <gstream.h>

void set_input_string(char const *s);

This function provides a way to specify an editable default string when inputting. Consider the following example:

 char buf[100];

 gs << "What’s your opinion about gstream?\n";
 gs.set_input_string("I think it is incredible wonderful!");

 gs.getline(buf, 100);

The user will see the following

 What’s your opinion about gstream?

 I think it is incredible wonderful!|

where the ‘|’ represents the cursor, and (s)he can edit the string, for example

 What’s your opinion about gstream?

 I think it is superior, fantastic and| wonderful!

resulting in ‘buf’ containing the string "I think it is superior, fantastic and wonderful!"
