     NAME
          idn_free - API function

     SYNOPSIS
          #include <idn.h>

          void idn_free(void * ptr);

     ARGUMENTS
          void * ptr  memory region to deallocate, or NULL.

     DESCRIPTION
          Deallocates memory region by calling free().  If  ptr is NULL no
          operation is performed.

          Normally applications de-allocate strings allocated by libidn by
          calling free() directly.  Under Windows, different parts of the same
          application may use different heap memory, and then it is important to
          deallocate memory allocated within the same module that allocated it.
          This function makes that possible.
