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.
