For the GNU C library, the permitted +values are listed by the \fBiconv --list\fP command, and all combinations +of the listed values are supported. +.PP +The resulting conversion descriptor can be used with \fBiconv\fP any number +of times. It remains valid until deallocated using \fBiconv_close\fP. +.PP +A conversion descriptor contains a conversion state. After creation using +\fBiconv_open\fP, the state is in the initial state. Using \fBiconv\fP +modifies the descriptor's conversion state. (This implies that a conversion +descriptor can not be used in multiple threads simultaneously.) To bring the +state back to the initial state, use \fBiconv\fP with NULL as \fIinbuf\fP +argument. +.SH "RETURN VALUE" +The \fBiconv_open\fP function returns a freshly allocated conversion +descriptor. In case of error, it sets \fBerrno\fP and returns (iconv_t)(-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" +UNIX98 +.SH "SEE ALSO" +.BR iconv (1), +.BR iconv (3), +.BR iconv_close (3) |
