  30 /*  FUNCTION
  31         Read one line of characters from the standard input stream into
  32         the buffer. Reading will stop, when a newline ('\n') is encountered,
  33         EOF or when the buffer is full. If a newline is read, then it is
  34         replaced by '\0'. The last character in the buffer is always '\0'.
  35
  36     INPUTS
  37         buffer - Write characters into this buffer
  38
  39     RESULT
  40         buffer or NULL in case of an error or EOF.

  46     BUGS
  47         Never use this function. gets() does not know how large the buffer
  48         is and will continue to store characters past the end of the buffer
  49         if it has not encountered a newline or EOF yet. Use fgets() instead.
