It's not just a bash variable, it's an environment variable. Have a look at getenv:

#include <stdlib.h>

...

// The value will be NULL if the variable doesn't exist
char* home = getenv("HOME");

You definitely want double quotes.

Thanks. fixed. Been a long while since I did any C coding. Been stuck in PHP purgatory for far too long.

You should have double quotes. getenv("HOME");
