47.Fa locale
48parameter.
49Any other components will be inherited from
50.Fa base .
51The
52.Fa mask
53is either
54.Fa LC_ALL_MASK ,
55indicating all possible locale components,
56or the logical OR of some combination of the following:
57.Bl -tag -width "LC_MESSAGES_MASK" -offset indent
58.It LC_COLLATE_MASK
59The locale for string collation routines.
60This controls alphabetic ordering in
61.Xr strcoll 3
62and
63.Xr strxfrm 3 .
64.It LC_CTYPE_MASK
65The locale for the
66.Xr ctype 3
67and
68.Xr multibyte 3
69functions.
70This controls recognition of upper and lower case, alphabetic or
71non-alphabetic characters, and so on.
72.It LC_MESSAGES_MASK
73Set a locale for message catalogs, see
74.Xr catopen 3
75function.
76.It LC_MONETARY_MASK
77Set a locale for formatting monetary values; this affects
78the
79.Xr localeconv 3
80function.
81.It LC_NUMERIC_MASK
82Set a locale for formatting numbers.
83This controls the formatting of decimal points in input and output of floating
84point numbers in functions such as
85.Xr printf 3
86and
87.Xr scanf 3 ,
88as well as values returned by
89.Xr localeconv 3 .
90.It LC_TIME_MASK
91Set a locale for formatting dates and times using the
92.Xr strftime 3
93function.
94.El
95This function uses the same rules for loading locale components as
96.Xr setlocale 3 .
97.Sh RETURN VALUES
98Returns a new, valid,
99.Fa locale_t
100or NULL if an error occurs.
101You must free the returned locale with
102.Xr freelocale 3 .
