.SH NAME
sasl_decode \- decode data received
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR ... ] \fIfile\fR ... \fB-lsasl\fR [ \fIlibrary\fR ... ]
#include <sasl/sasl.h>
\fBint\fR \fBsasl_decode\fR(\fBsasl_conn_t *\fR\fIconn\fR, \fBconst char *\fR\fIinput\fR, \fBunsigned\fR \fIinputlen\fR,
\fBconst char **\fR\fIoutput\fR, \fBunsigned *\fR\fIoutputlen\fR);
.fi
.SH DESCRIPTION
.sp
.LP
Use the \fBsasl_decode()\fR interface to decode data received. After
authentication, call this function on all data received. The data is decoded
from encrypted or signed form to plain data. If no security lay is negotiated,
the output is identical to the input.
.sp
.LP
Do not give \fBsasl_decode()\fR more data than the negotiated \fBmaxbufsize\fR.
See \fBsasl_getprop\fR(3SASL).
.sp
.LP
\fBsasl_decode()\fR can complete successfully although the value of
\fIoutputlen\fR is zero. If this is the case, wait for more data and call
\fBsasl_decode()\fR again.
.SH PARAMETERS
.sp
.ne 2
.na
\fB\fIconn\fR\fR
.ad
.RS 13n
