DbEnv::set_errcall

#include <db_cxx.h>


typedef void (*DbEnv::db_errcall_fcn)(const char *, char *);
void DbEnv::set_errcall(db_errcall_fcn);

Description

The DbEnv::set_errcall method is used to replace the mechanism for reporting error messages to the user. By default, DB writes error messages using the C library's stderr. To allow alternative styles of error reporting, set_errcall can be called with a single function pointer argument. The function must be defined with two arguments; the first will be the prefix string (set by set_errpfx), the second will be the error message string. It is up to this function to display the message in an appropriate manner.
