DbEnv::set_errfile

 APIRef 

#include <db_cxx.h>


void DbEnv::set_errfile(FILE *errfile);

Description

When an error occurs in the Berkeley DB library, an exception is thrown or an error return value is returned by the method. In some cases, however, the errno value may be insufficient to completely describe the cause of the error, especially during initial application debugging.

The DbEnv::set_errcall and Db::set_errcall methods are used to enhance the mechanism for reporting error messages to the application by setting a C library FILE * to be used for displaying additional Berkeley DB error messages. In some cases, when an error occurs, Berkeley DB will output an additional error message to the specified file reference.

Alternatively, you can use the DbEnv::set_error_stream method to display the additional information via an output stream, or the DbEnv::set_errcall method to capture the additional error information in a way that does not use either output streams or C library FILE *'s. You should not mix these approaches.

The error message will consist of the prefix string and a colon (":") (if a prefix string was previously specified using Db::set_errpfx or DbEnv::set_errpfx), an error string, and a trailing <newline> character.

This error logging enhancement does not slow performance or significantly increase application size, and may be run during normal operation as well as during application debugging.

The DbEnv::set_errfile interface may be used to configure Berkeley DB at any time during the life of the application.
