# sasl_errstring - Translate a SASL return code to a human-readable form

## Synopsis

    #include <sasl/sasl.h>

    const char * sasl_errstring(int saslerr,
        const char * langlist,
        const char ** outlang);

## Description

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.

  Parameters

    - 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).

## Return Value

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