31 function is the wide-character equivalent
35 It reads a wide character from \fIstream\fP and returns it.
36 If the end of stream is reached, or if \fIferror(stream)\fP becomes true,
39 If a wide-character conversion error occurs, it sets
40 \fIerrno\fP to \fBEILSEQ\fP and returns
45 function or macro functions identically to
47 It may be implemented as a macro, and may evaluate its argument
49 There is no reason ever to use it.

64 form a valid character.
75 In the absence of additional information passed to the
78 reasonable to expect that
80 will actually read a multibyte sequence
81 from the stream and then convert it to a wide character.
