This is useful for programs that need * to conditionally compile code with <literal>#ifdef</literal> blocks * depending on the version of librsvg that may be available during * compilation. * * Librsvg also provides a few global constants that can be used to * check the version of librsvg being used at run-time. This is * useful to know which version of librsvg is actually being used on * the system where the program is running. / /* * LIBRSVG_MAJOR_VERSION: * * This is a C macro that expands to a number with the major version * of librsvg against which your program is compiled. * * For example, for librsvg-2.3.4, the major version is 2. * * C programs can use this as a compile-time check for the required * version, but note that generally it is a better idea to do * compile-time checks by calling <ulink * url="https://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</ulink> * in your build scripts. * * Note: for a run-time check on the version of librsvg that your * program is running with (e.g. the version which the linker used for * your program), or for programs not written in C, use * @rsvg_major_version instead. / /* * LIBRSVG_MINOR_VERSION: * * This is a C macro that expands to a number with the minor version * of librsvg against which your program is compiled. * * For example, for librsvg-2.3.4, the minor version is 3. * * C programs can use this as a compile-time check for the required * version, but note that generally it is a better idea to do * compile-time checks by calling <ulink * url="https://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</ulink> * in your build scripts. * * Note: for a run-time check on the version of librsvg that your * program is running with (e.g. the version which the linker used for * your program), or for programs not written in C, use * @rsvg_minor_version instead. / /* * LIBRSVG_MICRO_VERSION: * * This is a C macro that expands to a number with the micro version * of librsvg against which your program is compiled. * * For example, for librsvg-2.3.4, the micro version is 4. * * C programs can use this as a compile-time check for the required * version, but note that generally it is a better idea to do * compile-time checks by calling <ulink * url="https://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</ulink> * in your build scripts. * * Note: for a run-time check on the version of librsvg that your * program is running with (e.g. the version which the linker used for * your program), or for programs not written in C, use * @rsvg_micro_version instead. / /* * LIBRSVG_VERSION: * * This is a C macro that expands to a string with the version of * librsvg against which your program is compiled. * * For example, for librsvg-2.3.4, this macro expands to * <literal>"2.3.4"</literal>. * * C programs can use this as a compile-time check for the required * version, but note that generally it is a better idea to do * compile-time checks by calling <ulink * url="https://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</ulink> * in your build scripts. * * Note: for a run-time check on the version of librsvg that your * program is running with (e.g. the version which the linker used for * your program), or for programs not written in C, use * @rsvg_version instead. / /* * LIBRSVG_CHECK_VERSION: * @major: component for the major version to check * @minor: component for the minor version to check * @micro: component for the micro version to check * * This C macro returns #TRUE if the the version of librsvg being * compiled against is the same or newer than the specified version. * * Note that this a compile-time check for C programs.
