[libvirt] [PATCHv2] Macro for testing the version you are compiling with

Added a macro similar to the GLib's GLIB_CHECK_VERSION so that one can simplydo something like: #if LIBVIRT_CHECK_VERSION(1,1,3) /* Call function here that appeared in 1.1.3 and newer */ virSomeNewFunction(); #endif --- include/libvirt/libvirt.h.in | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index 80b2d78..65f98c6 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -1466,6 +1466,20 @@ VIR_EXPORT_VAR virConnectAuthPtr virConnectAuthPtrDefault; #define LIBVIR_VERSION_NUMBER @LIBVIRT_VERSION_NUMBER@ +/** + * LIBVIRT_CHECK_VERSION: + * + * Macro for developers to easily check what version of the library + * their code is compiling against. + * e.g. + * #if LIBVIR_CHECK_VERSION(1,1,3) + * // some code that only works in 1.1.3 and newer + * #endif + */ +#define LIBVIRT_CHECK_VERSION(major,minor,micro) \ + ((((major) * 1000000) + ((minor) * 1000) + (micro)) <= \ + LIBVIR_VERSION_NUMBER) + int virGetVersion (unsigned long *libVer, const char *type, unsigned long *typeVer); -- 1.8.1.5
