write char[] to NSOutputStream and read from NSInputStream

Question

I am trying to write to NSoutputStream as below:

+(void)write:(char[])data
{
    int size=(sizeof data) / (sizeof data[0]);
    [outputStream write:(const uint8_t *)data maxLength:size];
}

is this right? Also how can I read NSInputStream into an char[].

Answer 1

No, it isn't right. Arrays are not pointers , hence the sizeof() operator here doesn't do what you think it does. Use an explicit length argument.

(Furthermore, sizeof(char) is always 1, so you don't have to spell it out.)
