Yeah ! You need to read the desired environment variable (like HOME), 
using a API like "|char *getenv(const char */name/);".

After read, you shall concatenate the 2 strings:

char *pHome;
char *pMyDir="mydir/mysubdir";
char sFullPath[_MAX_PATH];

pHome = getenv("HOME");
sprintf(sFullPath, "%s/%s", pHome, pMyDir);

WARNING: "sprintf()" isn't the faster way to build a concatenated 
string. If you'll need to repeat this in a long loop, try another way 
using only a single call to "strcat()".
