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

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