Fatal Error Messages

For fatal errors, use slapi_log_error_ex(). In many cases, you might return -1 after you log the message to indicate to Directory Server that a serious problem has occurred.

Example 4–5 Logging a Fatal Error Message

#include "slapi-plugin.h"
#include "example-com-error-ids.h" /* example.com unique
                                      error IDs file       */
int
foobar(Slapi_PBlock * pb)
{
    char * error_cause;
    int    apocalypse = 1;         /* Expect the worst.    */

    /* ... */

    if (apocalypse) {              /* Server to crash soon */
        slapi_log_error_ex(
            EXCOM_SERVER_MORIBUND, /* Unique error ID      */
            SLAPI_LOG_NO_MSGID,
            SLAPI_LOG_NO_CONNID,
            SLAPI_LOG_NO_OPID,
            "example.com: foobar in baz plug-in",
            "cannot write to file system: %s\n",
            error_cause
        );
        return -1;
    }
    return 0;
}

In this example, foobar() logs an error as Directory Server is about to crash.

If the plug-ins are internationalized, use macros, not literal strings, for the last two arguments to slapi_log_*_ex() functions.
