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);
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.
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.
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.
SASL_OK
The call to sasl_canon_user_t() was successful.
See sasl_errors(3SASL) for information on SASL error codes.
