Some days ago I asked this on the mailing list, in a function like:
static gboolean xunsetenv (char *varname) {
if (unsetenv(varname) != 0) {
return TRUE;
}
return FALSE;
}
How do replace if (unsetenv(varname) != 0) ? since OpenBSD's unsetenv is void.
Jim Razmus answered that one can do:
static gboolean xunsetenv (char *varname) {
unsetenv (varname);
return getenv (varname) == NULL ? TRUE : FALSE;
}
But, if I understand correctly, Thorsten Glaser rejected that answer,
because getenv fails for different reasons.
So, what is the proper wat to do this? Thanks
