My_getNEXTLINE

Ou comment S’ARRÊTER devant un mur

char	*get_next_line(const int fd)
{
  int		c;
  size_t	cursor;
  char		*line;

  cursor = 0;
  if ((line = malloc(sizeof(char) * (BUFFER_SIZE + 1))) == NULL)

My_get_NEXT_CONTENT_WALL

Quit à prendre un mur autant choisir le bon !

char	*get_next_content_wall(const int fd, char wall)
{

  size_t	cursor;
  char		*line;

  cursor = 0;
