sasl_callbacks(3)
NAME
  sasl_callbacks - How to work with SASL callbacks

SYNOPSIS
  #include <sasl.h>

DESCRIPTION
  sasl_callbacks are used when the application needs some information from
  the application. Common uses are for getting usernames and passwords.	 A
  client MUST specify what callbacks they support in the
  sasl_client/server_init or sasl_client/server_new calls. If an
  authentication mechanism needs a callback that the application does not
  state it supports, it cannot be used.

  If a callback has an id parameter that should be checked, make sure you are
  giving the appropriate value.

  If an application is using the client side of the library, the functions to
  handle the callbacks are not necessary. Instead the application may deal
  with callbacks via SASL_INTERACT. See sasl_client_start/stop for more
  information.
