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

 #include <sasl/sasl.h> 
 "const char * sasl_errstring(int " saslerr ", "  " const char * " langlist ", "  " const char ** " outlang ");" 

sasl_usererr 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 written by programmers (aka gobbledygook). Note that a server should call sasl_usererr on a return code first if the string is going to be sent to the client.

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.

It should be noted that 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.

RFC 4422 sasl(3), sasl_errdetail(3), sasl_errors(3)
