The `CommandLine` structure

The CommandLine structure provides access to the name and arguments used to invoke the currently running program. Additional information on the functions defined in this structure, particularly as stand-alone programs and program termination, can be found in Section 11.1.

Synopsis

signature COMMAND_LINE structure CommandLine : COMMAND_LINE

Interface

val name : unit -> string val arguments : unit -> string

Description

name (): returns the name used to invoke the current program.
arguments (): returns the argument list used to invoke the current program.
Implementation note:

The arguments returned may be only a subset of the arguments actually supplied by the user, since an implementation's run-time system may consume some of them.

Discussion

The precise semantics of the above operations are OS- and implementation-specific. For example, name might return the full pathname or just the base name. See also the implementation note under arguments.
