[ad_1] As pointed out by others, this statement suffers from undefined behavior: *(&x+5) += 7; Memory address &x+5 is outside the bounds of variable x. Writing to that address is a very bad idea. OP’s code sample exploits certain C compiler implementation details. Probably educational; it can be used to demonstrate how hackers can exploit … Read more

[ad_1] To print all bytes in an int? Remember that an int is 32-bit, which is four bytes. Reading it into a char buffer makes it easier to access those four bytes in the int. Edit: Little explanation of the int type… Lets say you have an int: int someIntValue = 0x12345678; This is stored … Read more
[ad_1] Presumably MAC_ADRESSES is not an array of pointers. NULL is a pointer (normally (void *)0 in C), so you can’t assign it to a non-pointer variable. Edit: Since your definition is char MAC_ADRESSES[MAX_LINES][100], you have a 2D array, not an array of pointers. You can’t store NULL in this array. You can wipe out … Read more

[ad_1] Well if you can’t use man, why not just search for it? Anyway you are using it wrong. If you want to read it by chunks you should do it like this // consider that we allocated enough memory for buffer // and buffer is byte array ssize_t r = 0, i = 0; … Read more
[ad_1] The simple answer that won’t help you much is that this is done for backwards compatibility with C, that has exactly the same syntax to define variables. The rationale for that design would have to come from the creators of C, and I don’t really know it. What I do know is that most … Read more
