HELPLIB.HLB  —  CRTL  getcwd  Arguments
 buffer

    Pointer to a character string large enough to hold the directory
    specification.

    If buffer is a NULL pointer, getcwd obtains size bytes of space
    using malloc. In this case, you can use the pointer returned by
    getcwd as the argument in a subsequent call to free.

 size

    The length of the directory specification to be returned.

  . . .

    An optional argument that can be either 1 or 0. If you specify 1,
    the directory specification is returned in OpenVMS format. If you
    specify 0, the directory specification (pathname) is returned in
    UNIX style format. If you omit this argument, getcwd returns the
    filename according to your current command-language interpreter
    (CLI).
