fcup-smsend[mult]: fix buglet in K&R C NULL pointer passing The only 100% safe way to pass a NULL pointer as a function argument in K&R C is to cast 0 to a pointer type; failing to do so may cause mysterious bugs (invalid stack frames or garbage in argument registers) on 64-bit machines. This issue has already been fixed in most of FC host tools, but I just found some missed spots: passing of NULL UDH to PDU encoding functions in fcup-smsend[mult] in the case of single (not concatenated) SMS.

#!/bin/sh

if [ $# != 1 ]
then
	echo "usage: $0 test_melody_name" 1>&2
	exit 1
fi

if [ ! -f "$1.src" ]
then
	echo "error: can't find $1.src" 1>&2
	exit 1
fi

exec ../fc-e1gen "$1.src" "$1.bin"
