Could anyone help me to solve a problem with nodejs and C library (call to
some dll methods)?
My dll have these methods:
void Open(char *Path);int Execute(TINData *InData,TOUData *OutData);void
Close(void);
with these data structures:
typedef struct {
char Value[8+1];
char Type [1+1];
int Id;
unsigned char Parity;} TINData
typedef struct {
char Cash[8+1];
char Telephone[11+1];
char CallType[3+1];
char CallResult[2+1];
char Description[24+1];} TOUTData
My nodejs code:
var ffi = require('ffi');var ref = require('ref');var StructType =
require('ref-struct');
var TINData = StructType({
'Value': 'string',
'Type': 'string',
'Id': 'int',
'Parity': 'string'});
var TOUTData = StructType({
'Cash': 'string',
'Telephone': 'string',
'CallType': 'string',
'CallResult': 'string',
'Description': 'string'});
var mylibrary = ffi.Library('OurLib.dll', {
'Open' : ['void', ['string']],
'Execute' : ['void', [TINData, TOUTData]],
'Close' : ['void', ['void']]});
myLibrary.Open('myConnection');
var myTINData = new TINData();
myTINData.Value = '00000010';
myTINData.Type = '1';
myTINData.Id = 123;
myTINData.Parity = '0';
