[GLLUG] ~ or $HOME ?

[Alain Williams]

I have just written a program that processes an xxxx.rc file:

* /etc/xxxx.rc

* ~/.xxxx.rc

I got a value for ~ from the password file - I was doing a getpwuid() anyway.

Should I instead use $HOME ? OK: $HOME and the value from the password entry
will be the same most of the time, but *most*, not always.

Any opinions on what the 'right' thing to do ? Options:

a) $HOME

b) getpwuid() (or similar)

c) $HOME, but if that is not defined: getpwuid()
