read() from stdin doesn't ignore newline

Question

I am using the following conditional statement to read from standard input.

if ((n = read(0,buf,sizeof(buf))) != 0)

When inputting data fro

Answer 1

You have to check the buffer yourself. e.g.

while((n = read(0,buf,sizeof(buf))) > 0) {
  if(buf[0] == '\n') // won't handle pressing 9 spaces and then enter
    continue;
  ... process input

}

or use e.g. fgets, and just strip off the \n

while(fgets(buf,sizeof buf,stdin) != NULL) {
  char *ptr;
  size_t len;

  if((ptr = strchr(buf,'\n')) != NULL) //strip newline
    *ptr = 0; 
  len = strlen(buf);
  if(len == 0)
   continue;
  ... process input 
}
