Why not just do:

void function( char *string )
{
	if( string == NULL ) {
		string = strdup( "default" );
	}

	/* ... */

	free( string );

}

int main()
{
	function( "moo" );
	function( NULL );
}

it does mean that you can't just call "function();" - you have to put
a NULL as the argument, but it works just fine.
