.TH ICONV_OPEN_INTO 3  "September 21, 2008" "GNU" "Linux Programmer's Manual"
.SH NAME
iconv_open_into \- initialize descriptor for character set conversion
.SH SYNOPSIS
.nf
.B #include <iconv.h>
.sp
.BI "int iconv_open_into (const char* " tocode ", const char* " fromcode ","
.BI "                     iconv_allocation_t* " resultp );
.fi
.SH DESCRIPTION
The \fBiconv_open_into\fP function initializes a conversion descriptor suitable
for converting byte sequences from character encoding \fIfromcode\fP to
character encoding \fItocode\fP.  The conversion descriptor is stored in the
memory pointed to by \fIresultp\fP.
.PP
The values permitted for \fIfromcode\fP and \fItocode\fP are the same as for
the function \fBiconv_open\fP.
.PP
After a successful return from this function, \fIresultp\fP can be be used
as an \fBiconv_t\fP object with the \fBiconv\fP function.
.SH "RETURN VALUE"
The \fBiconv_open_into\fP function fills \fB*\fP\fIresultp\fP and returns 0 if
it succeeds. In case of error, it sets \fBerrno\fP and returns \-1.
.SH ERRORS
The following error can occur, among others:
.TP
.B EINVAL
The conversion from \fIfromcode\fP to \fItocode\fP is not supported by the
implementation.
.SH "CONFORMING TO"
This function is implemented only in GNU libiconv and not in other \fBiconv\fP
implementations. It is not backed by a standard. You can test for its presence
through \fB(_LIBICONV_VERSION >= 0x010D)\fP.
