Thread: stopping a program

i write a program and i want to stop it by pressind " CTRL-D" .(press only once);

i also write a line thar stops the program but it stops it by pressing "CTRL-D"twice ,
what should i do

Code:

char buff[BUFSIZ];
while ( fgetc( buff, BUFSIZ, stdin ) != NULL ) {
  // do stuff
}

This should loop until you enter CTRL-D (once)

> i also write a line thar stops the program but it stops it by pressing "CTRL-D"twice
This can be because you have ununsed input

For example
ABCD\n
CTRL-D

Only needs you to press CTRL-D once

Whereas
ABCD CTRL-D
CTRL-D

Needs you to press CTRL-D twice
