Setting any of the LC_* parameters explicitly calls some locale stuff
(whether or not it is exported), apart from just setting the
parameters:
/**/
void
lcsetfn(Param pm, char *x)
{
char *x2;
struct localename *ln;
strsetfn(pm, x);
if ((x2 = getsparam("LC_ALL")) && *x2)
return;
queue_signals();
/* Treat empty LC_* the same as unset. */
if (!x || !*x)
x = getsparam("LANG");
/*
* If we've got no non-empty string at this
* point (after checking $LANG, too),
* we shouldn't bother setting anything.
*/
if (x && *x) {
for (ln = lc_names; ln->name; ln++)
if (!strcmp(ln->name, pm->node.nam))
setlocale(ln->category, unmeta(x));
}
unqueue_signals();
clear_mbstate(); /* LC_CTYPE may have changed */
inittyptab();
}
