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

Added a macro similar to the Linux kernel's KERNEL_VERSION so that you can simply do something like: #if LIBVIR_VERSION(1,1,3) <= LIBVIR_VERSION_NUMBER /* Call function here that appeared in 1.1.3 and newer */ virSomeNewFunction(); #endif --- include/libvirt/libvirt.h.in | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index 80b2d78..41a8c69 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -1466,6 +1466,16 @@ VIR_EXPORT_VAR virConnectAuthPtr virConnectAuthPtrDefault; #define LIBVIR_VERSION_NUMBER @LIBVIRT_VERSION_NUMBER@ +/** + * LIBVIR_VERSION: + * + * Macro for developers to easily check what version of the library + * their code is compiling against.
