Question

I need variable charSize. How do I do this in objective-c:

char *bufferData = new char[charSize]; //c++ notation

thx

Answer 1

You use malloc:

char *bufferData = malloc(charSize * sizeof(char));

(Technically the sizeof(char) isn’t necessary since chars are always of size 1, but I like to include it anyway so that it looks “wrong” if I accidentally do a malloc without a size.)

But depending on what you’re doing, you might want to look into NSString or NSData, the Cocoa classes for dealing with text and binary data, respectively. The rest of the Cocoa framework generally uses those.
