Hello,
I wrote this simple program which prints all the arguments given to a program.
My code is straightforward and this is it
Code:
#include <stdio.h>
#include <malloc.h>
int i = 0;
int main(int argc, char** argv)
{
printf("\nargc == [%d]",argc);
printf("\nthe arguments are ");
for(i=0;i<argc;i++)
{
printf(&q
Original source code :#include <stdlib.h>
#include <stdio.h>
#include <string.h>
int main(int argc, char** argv) {
int max = -1;
int mb = 0;
char* buffer;
if(argc > 1)
max = atoi(argv[1]);
while((buffer=malloc(1024*1024)) != NULL && mb != max) {
memset(buffer, 0, 1024*1024);
mb++;
printf("Allocated %d MB\n&quo
Hello All,
I am trying to call a function from the calling main program from a dlopened library function, below is the entire code, when I execute it it crashes with sigill. Can you guys help me out I guess I am missing out on the linker flag or something here.
I'm trying to make a program which is getting 2 pathes for files to main, and calling linux' cmp command in order to compare them.
If they equal, I want to return 2, and if they're different, 1.
#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/wait.h>
int main(int argc, const char* argv[])
{
pid_t pid;
int stat;
//child process
if ((pid=fork()
everyone!
Image that i have a program(usemalloc) like this:
#include <stdio.h>
#include <stdlib.h>
#define USER_BYTES_SIZE 100
int main(void){
char* userbytes = (char*)malloc(USER_BYTES_SIZE*sizeof(char));
if(!userbytes)
return 1;
for(int i = 0; i <= USER_BYTES_SIZE; i++){ // "i <= USER_BYTES_SIZE" leads to an off-by-one memory overrun.
userbytes[
I am getting an error that makes no sense.
To start off with this is a homework assignment for my Operating Systems course and I am stumped.
The prof wants us to read in a source code file and take out all the comment lines and then output the file back into a new source code file.
I am trying to compile a simple program using OpenCV in Ubuntu Quantal. I have installed all the OpenCV packages available.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char *argv[])
{
fork();
fork();
fork();
puts("hi");
return 0;
}
This program prints 8 times hi and exits,
Why? Is not each fork calls main recursively
as in:
f(): "hi"; f()
