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.
