. After numerous attempts, and numerous interesting results, I am no closer to the light.
How does one read a string, with spaces, from the console in a console app?
All I know officially is that you use cin >> to read in a string. Works great with single words, but anything else and the entire application devours itself.
I know there is a way to do this, I just don''t know how. All help is appreciated, as always.

If I wanted to read in a string I would just getchar() until i found ''\n'' or somesuch I guess.
while (buffer[i++] = (getchar()) != ''\n'');
I think that would work.

A wise man once said "A person with half a clue is more dangerous than a person with or without one."

Close, but backspaces, and the alternative enter key doesn''t work that way. getline works as long as the user doesn''t type too much.
For a good time hit Alt-F4! Go ahead try it, all the cool people are doing it.

some console code from my engine (using DirectInput, PressedKey is the number of the key in DInput). Have fun!
INT ManageConsole(int PressedKey, s_player &Player, Game_Msg &GMsg)
{
if((timeGetTime()-GMsg.ConsoleLetterTime>100) // (PressedKey!=GMsg.OldKey))
{
GMsg.OldKey=PressedKey;
GMsg.ConsoleLetterTime=timeGetTime();
switch(PressedKey)
{
case 88: return E_FAIL; break;
case 1: return E_FAIL; break;
case 15: {strcpy(GMsg.ConsoleText, " ");
GMsg.ConsoleCounter=0; Player.ConsoleOn=false;} break;
case 28: ConsoleMessage(GMsg, Player); GMsg.ConsoleCounter=0; break;
}//alter the following lines to specify which keys are valid
if((PressedKey>15 && PressedKey<28) // (PressedKey>29 && PressedKey<41) //
(PressedKey>43 && PressedKey<54) // (PressedKey==57) //
(PressedKey>1 && PressedKey<12))
{
GMsg.ConsoleText[GMsg.ConsoleCounter]=LetterConvert(PressedKey);
if(GMsg.ConsoleCounter<255)GMsg.ConsoleCounter++;
}
if(PressedKey==14)
{
GMsg.ConsoleText[GMsg.ConsoleCounter]='' '';
if(GMsg.ConsoleCounter>0)GMsg.ConsoleCounter--;
}
}
return 0;
}

I have already tried cin.getline().
The code just proceeds, and the variable it was supposed to write to is empty.

This function will read all characters until you press ENTER:
#include <stdio.h>
char *gets_safe(char *s, int maxlength)
{
fgets(s, maxlength, stdin);
return s;
}
Then simply call the function like this:
int main(void)
{
char string[100];
// Only take 99 characters.
gets_safe(string, 99);
return 0;
}
You could just use gets() instead of gets_safe(), but I like my own function more since it's a lot safter than gets() (no buffer overflows, or whatever it's called
)./. Muzzafarath

gets works fine, thanks. I am not really interested how safe it is .
As I stated before, I tried getline and the program just continued running without displaying a prompt.
