.SH DESCRIPTION
|
|
.LP
|
|
The \fIbtowc\fP() function shall determine whether \fIc\fP constitutes
|
|
a valid (one-byte) character in the initial shift
|
|
state.
|
|

|
The behavior of this function shall be affected by the \fILC_CTYPE\fP
|
|
category of the current locale.
|
|
.SH RETURN VALUE
|
|
.LP
|
|
The \fIbtowc\fP() function shall return WEOF if \fIc\fP has the value
|
|
EOF or if \fB(unsigned char)\fP \fIc\fP does not
|
|
constitute a valid (one-byte) character in the initial shift state.
|
|
Otherwise, it shall return the wide-character representation of
|
|
that character.
