wconv(3S)

NAME
     wconv: towupper, towlower,    wctrans, towctrans  - translation character
     functions and extensible translation functions

SYNOPSIS
     #include <ctype.h>
     #include <widec.h>
     #include <wctype.h>
     win_t towupper(win_t c);
     win_t towlower(win_t c);
     wctrans_t wctrans(const char *property);
     wint_t towctrans(wint_t wc, wctrans_t desc);

DESCRIPTION
     If the argument to towupper represents a lowercase letter of the ASCII or
     supplementary code sets, the result is the corresponding uppercase
     letter.  If the argument to towlower represents an uppercase letter of
     the ASCII or supplementary code sets, the result is the corresponding
     lowercase letter.  In the case of all other arguments, the return value
     is unchanged.  The table used for translation is generated by
     wchrtbl(1M).

     The wctrans function and towctrans function are extensible wide character
     translation functions.  The wctrans function returns a nonzero value of
     wctrans_t type that describes a translation between wide characters
     identified by the argument property, if the value is valid as the second
     argument to the towctrans function. Otherwise it returns zero.  tolower
     and toupper are available property names. The towctrans function returns
     the translated value of wc using the translation described by desc.

NOTES
     wctrans and towctrans are available with n32 and 64 C libraries for IRIX
     6.5.17 or later versions.
