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()".
