 NAME
sasl_canon_user_t - the canon user callback

 SYNOPSIS


cc [ flag ... ] file ... -lsasl [ library ... ]
#include <sasl/sasl.h>

int sasl_canon_user_t(sasl_conn_t *conn, void *context, const char *user,
 unsigned ulen, unsigned flags, const char *user_realm, char *out_user,
 unsigned *out_umax, unsigned *out_ulen);




 DESCRIPTION

The sasl_canon_user_t() interface is the callback function for an
application-supplied user canonical function. This function is subject to the
requirements of all canonical functions. It must copy the result into the
output buffers, but the output buffers and the input buffers can be the same.

 PARAMETERS
conn


The SASL connection context.



context


The context from the callback record.



user


User name. The form of user is not canonical.



ulen


Length of user. The form of ulen is not canonical.



flags


One of the following values, or a bitwise OR of both:
SASL_CU_AUTHID


Indicates the authentication ID is canonical



SASL_CU_AUTHZID


Indicates the authorization ID is canonical






user_realm


Realm of authentication.



out_user


The output buffer for the user name.



out_max


The maximum length for the user name.



out_len


The actual length for the user name.




 RETURN VALUES

Like other SASL callback functions, sasl_canon_user_t() returns an
integer that corresponds to a SASL error code. See <sasl.h> for a
complete list of SASL error codes.

 ERRORS
SASL_OK


The call to sasl_canon_user_t() was successful.





See sasl_errors(3SASL) for information on SASL error codes.
