.SH NAME
sasl_seterror \- set the error string
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR ... ] \fIfile\fR ... \fB-lsasl\fR   [ \fIlibrary\fR ... ]
#include <sasl/sasl.h>

\fBvoid\fR \fBsasl_seterror\fR(\fBsasl_conn_t *\fR\fIconn\fR, \fBunsigned\fR \fIflags\fR,
     \fBconst char *\fR\fIfmt\fR, ...);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBsasl_seterror()\fR interface sets the error string that will be returned
by \fBsasl_errdetail\fR(3SASL). Use \fBsyslog\fR(3C) style formatting, that is,
use \fBprintf()\fR\(emstyle with \fB%m\fR as the most recent \fBerrno\fR error.
.sp
.LP
The \fBsasl_seterror()\fR interface is primarily used by server callback
functions and internal plug-ins, for example, with the \fBsasl_authorize_t\fR
callback. The \fBsasl_seterror()\fR interface triggers a call to the SASL
logging callback, if any, with a level of \fBSASL_LOG_FAIL\fR, unless the
\fBSASL_NOLOG\fR flag is set.
.sp
.LP
Make the message string sensitive to the current language setting. If there is
no \fBSASL_CB_LANGUAGE\fR callback, message strings must be \fBi-default\fR.
Otherwise, UTF-8 is used. Use of \fIRFC 2482\fR for mixed-language text is
encouraged.
.sp
.LP
If the value of \fIconn\fR is \fINULL\fR, the \fBsasl_seterror()\fR interface
fails.
