Question

I have to write a simple program to output 16 bytes of data to a file at 0 and 48th position and have come up with this program:

#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main()
{
    int f = create("test.tmp",774);
    if(f>0)
    {
        write(f,"DEPARTMENT OF CS",16);
        lseek(f,48,SEEK_SET);
        write(f,"DEPARTMENT OF IS",16);
    }
    return 0;
}

What is wrong with this? It tells me when I compile using cc 7a.sh -ll that:

undefined to reference to ‘create’

Answer 1

There’s no function named create

It’s named creat
