Hello,
I am new to c and need help with a current program I am working on.
Currently, the program (code below) input is as follows:
program apple.test.com 51112
What I need is (essentially three arguments with a ':' space between the hostname and port number, and a third argument):
program apple.test.com:51112 usr/bin/test
where:
apple.test.com is argv[1]
51112 is argv[2]
usr/bing/test is argv[3]
Thanks guys.
Here is a bit of the current client file which needs to be modified.
_______________ _______________ __________
int main(int argc, char *argv[])
{
int sockfd, portno, n;
struct sockaddr_in serv_addr;
struct hostent *server;
char buffer[256];
// get proper number of input arguments before proceeding
if (argc != 3) {
fprintf(stderr, "usage %s <hostname> <port>\n", argv[0]);
exit(0);
}
portno = atoi(argv[2]);
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0)
error("ERROR opening socket");
server = gethostbyname(a rgv[1]);
if (server == NULL) {
fprintf(stderr, "ERROR, no such host\n");
exit(0);
}

run time parameters to main() are seperated by spaces, i.e. running the program
program apple.test.com: 51112 usr/bin/test
gives
apple.test.com: 51112 is argv[1]
usr/bin/test is argv[2]
you can then use function strstr() in <string.h> to extract apple.test.com and 51112 from argv[1], see

The short sample program listed below has some features that I find to be
bad style. In particular, they fail to communicate the connection between
names used in this program and the location in which they are declared and
or defined. I'd like to know if there are any features of this code you
believe represents bad programming technique. How would the feature be
better implemented?

int main(int argc, char *argv ) or int main(int argc, char **argv )
i.e. *argv or **argv
Why choose the latter?

I have my main function set up as
int main(int argv, char *argv)
so taht i can read in a variable which is passed to the program on the
command line. The problem is that main calls other functions and some

just int main() this would be no problem, i could just call main();
The problem is main needs parameters passed to it now. Would any1

I wonder how 'main(int argc, char ** argv)' is implemented? How
does it get
the string literals separated by whitespace from the stdin stream?
And is there any difference between 'char**' and 'char *'(the
second argument of function main)?
My initial purpose was to parse the input from the keyboard like
'main' does, code is here:
