Thread: function to replace system("pause");

Then you are out of luck looking for a portable solution. My solution waiting for enter isn't really portable either. But it should be good enough if it is only used for the problem "I cannot see what my program is doing because the window is closing", and I cannot see any other reason why anybody would use system("pause") in a real application ( see topic. )

im still pretty new to C, any good site where i can get conio.h, mine doesnt come with it i think...

thanks, that was right - i checked my "bin" folder and i do have conio.h ...but when i try to compile a program with it, it says it doesnt exist in the libary - "clrscr"
for ex.

Code:

#include <stdio.h>
#include <conio.h> 

int main()
{
  printf("say this so something may be cleared");
  sleep ( 1200 );
  clrscr();   /* It doesnt clear, i get error weh compileing,, (undefined reference to 'clrscr' ) */
  return(0);
}

its supposed to clear it, but its not found
+ im pretty sure clrscr is in the libary

yea, it is - "dev c++ 4"

Did you click the link in Dave_Sinkula's post?

Code:

#include <stdio.h>
#include <conio.h>
#include <windows.h> 

int main()
{
  printf("say this so something may be cleared");
  Sleep ( 1200 );// Sleep NEEDS to be capitalized
                 //make sure you include windows.h!
  system("cls"); //not great  but it works on dev++
  printf("hello there again\n");
  getch(); //pause the program
}

Of course, not everyone is using windows and in general 'system' commands are frowned upon. Check out the FAQ for more info.

i got mine to work btw - i had to include conio.c instead of conio.h (???)

The problem may have been that you needed to link the program to the conio library.
