Get OS name with C [Linux, portable for distros: Centos, Debian, Fedora, OpenSUSE, RedHat, Ubuntu]

Question

I know I can check my OS name with this simple command: lsb_release -ds. But I also know, that its not portable on all platforms where I need it. I tried struct utsname info; and uname(&info) and it works great but gives me only "base" name - "Linux".

Is there any portable (C) way of getting full OS name? Portable between Centos, Debian, Fedora, OpenSUSE, RedHat, Ubuntu at least? Cheers

Here is the C code that says the name of the OS. You can also edit the code for other various purpose, by using the same logic.

#include<stdio.h>

int main()
{
    FILE *fp;
    char buffer[50] = " ";
    fp = popen("lsb_release -ds", "r");
    fgets(buffer, 50, fp);
    pclose(fp);
    printf("Name of the OS is : %s",buffer);
    return 0;
}
