I'm using node-ffi and I have a structure that needs to be passed. A few of the variables in the structure are arrays. How do I define this in the JavaScript wrapper?
C header:
typedef struct
{
unsigned char myUChar;
float fmyFloat;
float arrayFloat[ARRAY_SIZE];
} sMyStruct;
JavaScript wrapper:
var ffi = require('ffi');
var Struct require('ref-struct');
var sMyStruct = Struct({
'myUChar': 'uchar',
'fmyFloat': 'float',
'arrayFloat[ARRAY_SIZE]': 'float' // Would this work??
});
Is there a tutorial which indicates all of the variables that can be passed into node-ffi anyone can point me to? (For example can I actually pass 'uchar'?)
Turns out the correct way to declare the array in a struct is actually now:
var Struct require('ref-struct');
var ArrayType require('ref-array');
var sMyStruct = Struct({
'arrayFloat': ArrayType('float', 10) // array of floats, length 10
});
I still need to test this a bit more thoroughly, and as far as a list of types goes I found a decent one here: https://www.npmjs.com/package/node-ffi
