sasl_seterror - set the error string

void sasl_seterror(sasl_conn_t *conn, unsigned flags,

const char *fmt, ...);

The sasl_seterror() interface sets the error string that will be returned by sasl_errdetail(3SASL). Use syslog(3C) style formatting, that is, use printf()—style with %m as the most recent errno error.

The sasl_seterror() interface is primarily used by server callback functions and internal plug-ins, for example, with the sasl_authorize_t callback. The sasl_seterror() interface triggers a call to the SASL logging callback, if any, with a level of SASL_LOG_FAIL, unless the SASL_NOLOG flag is set.

Make the message string sensitive to the current language setting. If there is no SASL_CB_LANGUAGE callback, message strings must be i-default. Otherwise, UTF-8 is used. Use of RFC 2482 for mixed-language text is encouraged.

If the value of conn is NULL, the sasl_seterror() interface fails.


The sasl_conn_t for which the call to sasl_seterror() applies.


If set to SASL_NOLOG, the call to sasl_seterror() is not logged.


A syslog(3C) style format string.
