NAME

       IXP_API, IXP_NEEDAPI, IXP_MAXAPI, IXP_ASSERT_VERSION

SYNOPSIS

       #include <ixp.h>

       #define IXP_API ...

       #define IXP_NEEDAPI ...

       #define IXP_MAXAPI ...

       #define IXP_ASSERT_VERSION ...

DESCRIPTION

       IXP_API contains the current libixp API revision number.

       IXP_NEEDAPI,  if  defined before ixp.h is included, directs the header to present an older version of the
       libixp API. This allows code written for older versions of  libixp  to  compile  against  newer  versions
       without  modification.  It  does  not,  however,  ensure that it will link against a different version of
       libixp than the ixp.h header belongs to.

       IXP_MAXAPI, if defined before ixp.h is included, prevents code from compiling with  a  newer  version  of
       libixp than specified.

       When  inserted  into any function, IXP_ASSERT_VERSION ensures that the resulting object will fail to link
       link against any version of libixp with a different API version than it was compiled against.
