  24         char * buffer)

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

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