Valgrind Tutorial - Part 5

Errors Occur Due to Invalid System Call Parameter can be found using valgrind

int main(void)
{
        int *ptr;
        ptr = malloc(10);
        read(0, ptr, 100);        /* Error: unaddressable bytes */
        free(ptr);
        return 0;
}

You can see the following code we allocated 10 bytes and we are trying to read 100 bytes from stdin(standard input). Run the following commands gcc -o app app.c -g valgrind --tool=memcheck --leak-check=yes ./app
