.PP
\fBParameters:\fP
.RS 4
\fIin\fP an UCS4 string to convert

.SS "int wind_ucs2read (const void * ptr, size_t len, unsigned int * flags, uint16_t * out, size_t * out_len)"
Read in an UCS2 from a buffer\&.

\fIptr\fP The input buffer to read from\&. 
.br
\fIlen\fP the length of the input buffer\&.

.RE
.PP
if len is zero, flags are unchanged
.PP
if len is odd, WIND_ERR_LENGTH_NOT_MOD2 is returned
.PP
If the flags WIND_RW_BOM is set, check for BOM\&. If not BOM is found, check is LE/BE flag is already and use that otherwise fail with WIND_ERR_NO_BOM\&. When done, clear WIND_RW_BOM and the LE/BE flag and set the resulting LE/BE flag\&.
.SS "int wind_ucs2utf8 (const uint16_t * in, size_t in_len, char * out, size_t * out_len)"
