NAME

	CheckRexxMsg - Check if a RexxMsg is from ARexx

SYNOPSIS

	result = CheckRexxMsg(message)
	D0                    A0
	BOOL CheckRexxMsg(struct RexxMsg *);

FUNCTION

	This function checks to make sure that the message is from ARexx
	directly.  It is required when using the Rexx Variable Interface
	routines (RVI) that the message be from ARexx.
	While this function is new in the V37 amiga.lib, it is safe to
	call it in all versions of the operating system.  It is also
	PURE code, thus usable in resident/pure executables.

NOTES

	This is a stub in amiga.lib.  It is only available via amiga.lib.
	The stub has two labels.  One, _CheckRexxMsg, takes the arguments
	from the stack.  The other, CheckRexxMsg, takes the arguments in
	registers.

EXAMPLE

	if (CheckRexxMsg(rxmsg))
	{
		/* Message is one from ARexx */
	}

INPUTS

	message		A pointer to the RexxMsg in question

RESULT

	result		A boolean - TRUE if message is from ARexx.
