NSData object trouble with <16KB


  • Subject: NSData object trouble with <16KB
  • From: "David Piasecki" <email@hidden>

To pass data into an NSImage object, I first pass data into an NSData
object by calling the initWithBytes:length method. This works fine for
data lengths larger than 16KB. I specify the size of the data because I
ran into a problem today where any time I try to pass an NSData object
less than 16KB (say, 13,700 bytes), after the method call...

NSData *data = [NSData alloc];
[data initWithBytes:getData() length:getDataLength()];

getData() returns a char *
getDataLength() returns an int

The "data" ends up being of size 0 bytes. If the size of the data I
pass in is greater than 16KB, there is no problem. Unfortunately, I may
have data sizes smaller than 16KB. Has anyone ran into this problem,
and do you know of some way around it, or perhaps I'm doing something
wrong?

Thanks,
David
