- the canon user callback
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.
The SASL connection context.
The context from the callback record.
User name. The form of user is not canonical.
Length of user. The form of ulen is not canonical.
One of the following values, or a bitwise OR of both:
Indicates the authentication ID is canonical
Indicates the authorization ID is canonical
Realm of authentication.
The output buffer for the user name.
The maximum length for the user name.
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.
The call to sasl_canon_user_t() was successful.
See sasl_errors(3SASL) for information on SASL error codes.
