.TH SASL_ERRSTRING 3SASL "Oct 14, 2003"
.SH NAME
sasl_errstring \- translate a SASL return code to a human-readable form
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR ... ] \fIfile\fR ... \fB-lsasl\fR   [ \fIlibrary\fR ... ]
#include <sasl/sasl.h>

\fBconst char *\fR \fBsasl_errstring\fR(\fBint\fR \fIsaslerr\fR, \fBconst char *\fR\fIlanglist\fR,
     \fBconst char **\fR\fIoutlang\fR);

.SH DESCRIPTION
.sp
.LP
The \fBsasl_errstring()\fR interface is called to convert a SASL return code
from an integer into a human readable string.
.sp
.LP
You should not used the \fBsasl_errstring()\fR interface to extract error code
information from SASL. Applications should use \fBsasl_errdetail\fR(3SASL)
instead, which contains this error information and more.
.sp
.LP
The \fBsasl_errstring()\fR interface supports only \fBi-default\fR and
\fBi-local\fR at this time.
.SH PARAMETERS
.sp
.ne 2
.na
\fB\fIsaslerr\fR\fR
.ad
.RS 12n
The error number to be translated.
.RE

.sp
.ne 2
.na
\fB\fIlanglist\fR\fR
.ad
.RS 12n
A comma-separated list of languages. See \fIRFC 1766\fR. If the\fIlanglist\fR
parameter has a\fINULL\fR value, the default language,\fBi-default\fR, is used.
.RE

.sp
.ne 2
.na
\fB\fIoutlang\fR\fR
.ad
.RS 12n
The language actually used. The \fIoutlang\fR parameter can be \fINULL\fR. The
returned error string is in \fBUTF-8\fR.
.RE

.SH RETURN VALUES
.sp
.LP
\fBsasl_errstring()\fR returns the string that describes the error that
occurred, or \fINULL\fR, if there was an error retrieving it.
