CHARACTER CONVERSION MACROS
These macros perform simple case conversions on Latin characters in
Process Code, wchar_t, from the primary and supplementary codesets,
by table lookup.
- towupper(c)
-
converts the lower-case Latin character
c
to its upper-case equivalent. If
c
is not a lower-case Latin character
c
is returned.
- towlower(c)
-
converts the upper-case character
c
to its lower-case equivalent. If
c
is not an upper-case Latin character
c
is returned.
SEE ALSO
ctype.3c
setlocale.3c
iswalpha.3i
stdio.3s
NOTES
towupper
and
towlower
can be used safely in a multi-thread application, as long as
setlocale.3c
is not being called to change the locale.
