@settitle DB_ENV->set_lg_max
@c man title db_del tokudb
@unnumberedsubsec Synopsis
@c man begin SYNOPSIS
@code{#include <db.h>}
@noindent
@code{int DB_ENV->set_lg_max(DB_ENV *}@var{env}@code{, u_int32_t }@var{lg_max}@code{);}
@code{int DB_ENV->get_lg_max(DB_ENV *}@var{env}@code{, u_int32_t*}@var{lg_max_p}@code{);}
@c man end
@unnumberedsubsec Description
@c man begin DESCRIPTION
Set or get the maximum size, in bytes, of any given log file.
When logging is configured, the default maximum log size is 100MiB.
It is possible that a log file will be larger than @var{lg_max}: The
logs comprise log entries, and TokuDB always writes a complete log
entry into a log file. Thus if a log entry is larger than
@var{lg_max}, then the resulting log file could be larger.
You may call @code{DB_ENV->set_log_max} at any time on any environment
that has been created but hasn't yet been closed. Subsequently
written log files will be smaller than the specified size.
@c man end
@unnumberedsubsec Parameters
@c man begin PARAMETERS
@table @var
@item env
The @code{DB_ENV} handle.
@item lg_max
For @code{DB_ENV->set_log_max}, the new maximum logfile size, in bytes.
@item lg_max_p
For @code{DB_ENV->get_log_max}, the return result will be stored in @code{*}@var{lg_max_p}.
@end table
@c man end
@unnumberedsubsec Return Value
@c man begin RETURNVALUE
Returns zero on success.
@c man end
