The < code class = "methodname" > DbEnv::stat_print()< / code > method displays the default statistical
information. The information is printed to a specified output channel
(see the < a class = "xref" href = "envset_msgfile.html" title = "DbEnv::set_msgfile()" > DbEnv::set_msgfile()< / a >
method for more information), or passed to an application callback
function (see the < a class = "xref" href = "envset_msgcall.html" title = "DbEnv::set_msgcall()" > DbEnv::set_msgcall()< / a >
method for more information).
