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.
