NAME

       XltCheckArgSize - Convenience macro for asserting that an ArgList is large enough.

SYNOPSIS

       #include <Xlt/Xlt.h>

       void XltCheckArgSize(a, n)
	    Arg a[];
	    Cardinal n;

DESCRIPTION

       XltCheckArgSize simply asserts (using assert(3)) that a contains at least n elements.  This macro will generally be used with arrays of Arg
       but it will work with any array (such as arrays of strings that you are about to pass to execvp(3) and execv(3)).

       If you've ever debugged a stack corruption because you said "Arg a[3]" when you meant "Arg a[4]", you'll understand why	you  want  to  use
       this macro.

       Note that the a parameter must be an array, a pointer will not work.

RETURN VALUE

       None but it may cause abort(3) to be called.
