Node FFi accesing CTAPI
1
So I have the CT-API header that looks like this
char LINKAGE CT_init (
CTAPI_USHORT Ctn, /* Terminal Number */
CTAPI_USHORT pn /* Port Number */
);
char LINKAGE CT_close(
CTAPI_USHORT Ctn /* Terminal Number */
);
char LINKAGE CT_data(
CTAPI_USHORT ctn, /* Terminal Number */
unsigned char *dad, /* Destination */
unsigned char *sad, /* Source */
CTAPI_USHORT lc, /* Length of command */
unsigned char *cmd, /* Command/Data Buffer */
unsigned short *lr, /* Length of Response */
unsigned char *rsp /* Response */
);
When i call CT_init from my js code it works fine, but, when trying to call CT_data, I get an invalid data error.
This is my NodeJS
var ffi = require('ffi');
var ref = require('ref');
var libm = ffi.Library("C:\Windows\System32\CTPCSC31x64.dll", {
'CT_init' : [ ref.types.char, [ ref.types.uint, ref.types.uint ] ],
'CT_close': [ ref.types.char, [ ref.types.ushort ] ],
'CT_data' : [ref.types.char, [
ref.types.ushort,
ref.refType(ref.types.uchar),
ref.refType(ref.types.uchar),
ref.types.ushort,
ref.refType(ref.types.uchar),
ref.refType(ref.types.ushort),
ref.refType(ref.types.uchar)
]]
});
const command = new Buffer([0x20, 0x10, 0x00, 0x00, 0x00]);
const response = ref.alloc(ref.types.uchar)
const dest = new Buffer([0x02]);
const src = new Buffer([0x01]);
const response_l= new Buffer([0xFF]);
try {
console.log(JSON.stringify(command), JSON.stringify(dest), JSON.stringify(src), JSON.stringify(response));
console.log(libm.CT_init(0, 0));
console.log(libm.CT_data(0, dest, src, command.length, command , response_l, response));
console.log(libm.CT_close(0));
} catch(error) {
console.log(error);
}
