WriteFile writes zero's instead of my bytes

Code in C++:

short buffer[6];
buffer[0] = 1;
buffer[1] = 2;
buffer[2] = 3;
buffer[3] = 4;
buffer[4] = 5;
buffer[5] = 6;
short *p = &buffer[0];
int bufflen = 6;
int ret;
WriteFile(g_handle, p, bufflen, &ret, NULL);

After executing ret = 6 and WriteFile is a success. But when i open file with hex editor i see this:

01 00 02 00 03 00

So basically WriteFile wrote my byte then zero, then my byte, then zero again. Is this bug? Or i am doing something wrong? Thanks for help.

If I call with bufflen = 12 then ret = 12 and in file:

01 00 02 00 03 00 04 00 05 00 06 00.

This is confusing...

I thought that short is 8bit unsigned integer, and it turns out it is 16bit integer. Sorry about that. Will use unsigned char.

Seems pretty normal to me. You should use:

Code:

---

WriteFile(g_handle, p, sizeof(buffer), &ret, NULL);

Each 'short' that you write puts two bytes in the file, the low byte followed by the high byte.
