38 .Nd convert a wide-character code to a character
44 .Fn wctomb "char *mbchar" "wchar_t wchar"
48 function converts a wide character
50 into a multibyte character and stores
53 The object pointed to by
55 must be large enough to accommodate the multibyte character, which
62 pointer returns nonzero if the current locale requires shift states,
64 if shift states are required, the shift state is reset to the initial state.
72 function returns nonzero if shift states are supported,
79 the number of bytes processed in
81 or \-1 if no multibyte character
82 could be recognized or converted.
85 internal conversion state is undefined.
89 function will fail if:
92 An invalid multibyte sequence was detected.
94 The internal conversion state is invalid.
