.SH DESCRIPTION
|
2005-10-19 06:54:38 +00:00
|
|
|
The \fBwctob\fP() function tests whether the multi-byte representation of the
|
2004-11-03 13:51:07 +00:00
|
|
|
wide character \fIc\fP, starting in the initial state, consists of a single
|
|
|
|
byte. If so, it is returned as an unsigned char.
|
|
|
|
.PP
|
|
|
|
Never use this function. It cannot help you in writing internationalized
|
|
|
|
programs. Internationalized programs must never distinguish single-byte and
|
|
|
|
multi-byte characters.
|
|
|
|
.SH "RETURN VALUE"
|
2005-10-19 06:54:38 +00:00
|
|
|
The \fBwctob\fP() function returns the single-byte representation of \fIc\fP,
|
2004-11-03 13:51:07 +00:00
|
|
|
if it exists, of EOF otherwise.

.SH NOTES
|
2005-10-19 06:54:38 +00:00
|
|
|
The behaviour of \fBwctob\fP() depends on the LC_CTYPE category of the
|
2004-11-03 13:51:07 +00:00
|
|
|
current locale.
|
|
|
|
.PP
|
|
|
|
This function should never be used. Internationalized programs must never
|
|
|
|
distinguish single-byte and multi-byte characters. Use the function
|
2005-10-19 08:35:30 +00:00
|
|
|
\fBwctomb\fP() instead.
