RTParams
is a private interface.
INTERFACE RTParams;
This interface provides access to the runtime
arguments from the
command line. Command line arguments that begin @M3
are considered
runtime
arguments. They are removed from the usual (argc, argv) list
of arguments very early in initialization. A runtime argument has the
form @M3x
or @M3x=y
. x
is the name
of the argument, y
is its
value
, and x=y
is the full
argument. If =y
is missing,
is
the argument's value.
VAR (*READONLY*) NumParameters: CARDINAL;
Parameters are indexed from 0
to NumParameters-1
.
PROCEDURE Nth (n: INTEGER): TEXT;
returns the n
-th full
argument. If n
is not in [0..NumParameters-1]
,
NIL
is returned.
PROCEDURE IsPresent (n: TEXT): BOOLEAN;
returns TRUE
iff n
is the name of a defined runtime argument.
PROCEDURE Value (n: TEXT): TEXT;
returns the value of the runtime argument with name n
. If n
is not
the name of a runtime argument, NIL is returned. If n
is the name of
an argument that was specified as @M3n
, the empty string
is
returned.
PROCEDURE RawValue (n: TEXT): ADDRESS;
returns the C char*
that corresponds to the value.
PROCEDURE Init ();
called by the runtime initialization code
END RTParams.
