javascript - node ffi struct variable array -


i'm using node-ffi , have structure needs passed. few of variables in structure arrays. how define in 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'  // work?? });

is there tutorial indicates of variables can passed node-ffi can point me to? (for example can pass 'uchar'?)

turns out correct way declare array in struct 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 test bit more thoroughly, , far list of types goes found decent 1 here: https://www.npmjs.com/package/node-ffi

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
