NAME

       bson_zero_free()  -  This  function behaves like bson_free() except that it zeroes the memory first. This
       can be useful if you are storing passwords or other similarly important data. Note that if  it  truly  is
       important, you probably want a page protected with mlock() as well to prevent it swapping to disk.

SYNOPSIS

       void

PARAMETERS

       mem    A memory region.
