This header provides the Eet management functions.
Typedef Documentation
Eet_Version
This is the Eet version information structure that can be used at runtiime to detect which version of eet is being used and adapt appropriately as follows for example:. .PP
#if defined(EET_VERSION_MAJOR) && (EET_VERSION_MAJOR >= 1) && defined(EET_VERSION_MINOR) && (EET_VERSION_MINOR > 2) printf('Eet version: %i.%i.%i, eet_version->major, eet_version->minor, eet_version->micro); if (eet_version->revision > 0) { printf(' Built from SVN revision # %i, eet_version->revision); } #endif
Note the if check can be dropped if your program refuses to compile or work with an Eet version less than 1.3.0.
