Hello all.. Sorry to keep bothering everyone with C questions, but this
one has me totally stumped..
I need to pass some data (in the form of a char* buffer) into a Unix
library function. I'm getting my data from an NSData object using
GetBytes:range:. My problem is that my buffers are not working.
i have:
char *buffer;
buffer = malloc(bufferSize);
NSLog(@"buffer size is: %i", sizeof(buffer));
here is where the problem is. the log output is 'buffer size is: 4', even
when i change the malloc
statement to read buffer = malloc(129) (129 is the size of the buffer i
need in my test case).
any ideas?
Try using malloc_size(buffer)
sizeof(buffer) will return the size of the buffer variable instead.
