sasl_errstring - Cyrus SASL documentation

#include <sasl/sasl.h>
const char * sasl_errstring(int saslerr,

const char * langlist,
const char ** outlang);

sasl_errstring is called to convert a SASL return code (an integer) into a human readable string. At this time the only language available is American English. Note that if the string is going to be sent to the client, a server should call sasl_usererr(3) on a return code first.
  • saslerr – specifies the error number to convert.
  • langlist – is currently unused; Use NULL.
  • outlang – specifies the desired RFC 1766 language for output. NULL defaults to “en‐us”; currently the only supported language.


This function is not the recommended means of extracting error code information from SASL, instead application should use sasl_errdetail(3), which contains this information (and more).


Returns the string. If langlist is NULL, US‐ASCII is used.
