gcc: libraries for copying files, ftp, data output ?

frenchn00b · 08-28-2007, 03:54 PM

Learning gcc slowly. I am now with files and output. I would like to send my results to my internet other pc, via ftp. Has someone any idea ? thanks

Please find the code :

Quote:

#include "stdio.h"
#include "assert.h"
#include "complex.h"
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <time.h>
#include <stdio.h>
#include <stdlib.h>

int main(int argc,
char **argv)
{
printf("Uploading\n");

execlp("ftp", "ftp", "10.1.1.56", "login@password", "file1tobeuploaded.zip", (char *) 0);

return 0;

}

Unless the program you are invoking with execlp() gets all of it's information from the commandline, you will need to use something like popen() to invoke it, in order to feed the program its required standard input. See this page on Beej's Guide to UNIX IPC
--- rod.

and could go gcc :

Code:

copy file1 file2

without any use of execlp ??

I need expert, gcc is really powerful.

looks like in this direction ....

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <unistd.h>

int main()
{
int pfds[2];
char buf[30];

if (pipe(pfds) == -1) {
perror("pipe");
exit(1);
}

printf("writing to file descriptor #%d\n", pfds[1]);
write(pfds[1], "test", 5);
printf("reading from file descriptor #%d\n", pfds[0]);
read(pfds[0], buf, 5);
printf("read \"%s\"\n", buf);
}

thank you, I am trying to understand. I had a good book of C, 2 years ago, but where it is ?
