Programming :: Best Way To Flush A Character Array
Aug 2, 2010I believe I have unwanted ' characters left in a 9 element character array that are causing subsequent operations with it to fail. I see wildly differing views on the web on the proper way to flush 'em. It's clearly not as simple as it would appear at first sight. What's currently the best (or else "least deprecated") method?

Programming :: Structure Pointing To Character Array
Aug 9, 2010I am currently writing a program using raw sockets. This program is used to send out ARP reply frames. The problem that I have is that I do not seem to be able to fill out a structure that is pointing to part of a character array.
Code:
struct eth_header *eth;
struct arp_header *arp;
char buf[8];
eth = (struct eth_header *)buf;
arp = (struct arp_header *)(buf+sizeof(struct arp_header));
Whilst I can fill out the variables of eth, I cannot fill out the variables of arp. If I fill them out and then send the contents of the array using send to, only the first structure (the ethernet header) is sent out. The rest of the data appears to be the original junk data in the array. I have checked the address of the structure pointer and it is pointing to the right place in the array. If I write a raw sockets program that uses an IP header struct and TCP header struct I can point these into the array and write to both of them without any issues.
The difference here is that the call to socket is different:
Code:
/* For ethernet */
fd = socket(AF_INET, SOCK_PACKET, htons(ETH_P_ARP));
/* For IP */
fd = socket(AF_INET, SOCK_RAW, IPPROTO_RAW);
If I just create one structure containing all of the variables needed this gets around the issue, however, I would like to know what I am doing wrong in the first instance.
Programming :: SED Assistance: Add Character In The Middle Of A String?
Oct 20, 2010I have a folder of MP3s, where some have <artist>- <song> and others have <artist> - <song>. I wanted to make all of them say <artist> - <song>
The command that works for me was
for i in *[a-Z]-*; do mv "$i" "`echo $i | sed 's/-/ -/g'`"; done
but if I -hadn't- used ls with my parameters to filter out the valid results, how would I have done this with sed? I got close with:
ls | sed -e 's/(.*)[a-Z]-(.*)/1 - 2/'
but with the above I lose the [a-Z] character that I used to match with (and I need to keep that).

Programming :: C: How Is A String Array Stored In Memory
Jan 12, 2009I need to call a function that takes a string array as argument, declared like this:Code:int someFunction(/* some parameters... */, const char* s[]);I'd like to know how to allocate memory for the string array. I know a string is an array of chars and an array is a pointer to the first element, then a string array should simply be a two dimensional char array. But is it a single memory block where all strings are stored consecutively?? Or is it a base vector where each element is a pointer to a separate memory block that contains a single string?More specifically: should I malloc() a single memory block large enough for all the strings? or should I allocate separate blocks for each string plus an extra one for the base vector?
