It then determines the wide-character code for the value of type \fBwchar_t\fR that corresponds to that character. (The value of the wide-character code corresponding to the null byte is 0.) If the character is valid and \fIpwc\fR is not a null pointer, \fBmbtowc()\fR stores the wide-character code in the object pointed to by \fIpwc\fR. .sp .LP A call with \fIs\fR as a null pointer causes this function to return \fB0\fR. The behavior of this function is affected by the \fBLC_CTYPE\fR category of the current locale. At most \fIn\fR bytes of the array pointed to by \fIs\fR will be examined. .SH RETURN VALUES .sp .LP If \fIs\fR is a null pointer, \fBmbtowc()\fR returns \fB0\fR. If \fIs\fR is not a null pointer, \fBmbtowc()\fR returns \fB0\fR (if \fIs\fR points to the null byte), the number of bytes that constitute the converted character (if the next \fIn\fR or fewer bytes form a valid character), or \fB\(mi1\fR and may set \fBerrno\fR to indicate the error (if they do not form a valid character). .sp .LP In no case will the value returned be greater than \fIn\fR or the value of the \fBMB_CUR_MAX\fR macro. .SH ERRORS .sp .LP The \fBmbtowc()\fR function may fail if: .sp .ne 2 .mk .na \fB\fBEILSEQ\fR\fR .ad .RS 10n .rt Invalid character sequence is detected. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
