- check an APOP challenge or response
cc [ flag ... ] file ... -lsasl [ library ... ] #include <sasl/sasl.h> int sasl_checkapop(sasl_conn_t *conn, const char *challenge, unsigned challen, const char *response, unsigned resplen);
The sasl_checkapop() interface checks an APOP challenge or response. APOP is an option POP3 authentication command that uses a shared secret password. See RFC 1939.
If sasl_checkapop() is called with a NULL challenge, sasl_checkapop() will check to see if the APOP mechanism is enabled.
The sasl_conn_t for which the request is being made
The challenge sent to the client
The length of challenge
The client response
The length of response
sasl_checkapop() returns an integer that corresponds to a SASL error code.
Indicates that the authentication is complete
All other error codes indicate an error situation that must be handled, or the authentication session should be quit. See sasl_errors(3SASL) for information on SASL error codes.
