How to get Package version?

[fechen]

Please help me to find the C function to get an RPM package version nubmer? I need to write an application to collect several packages' version information and I hate to use a command line, such as "rpm -qa"

In another word, I'd like to know how exactly RPM gets the package version?

If you know where I can download the source code of RPM and which C file to look into, that would be great, too.

Any hint helps. Thanks in advance

RPM is maintained at

http://www.rpm.org.

There is a documentation of their API here:

Any idea which file(s) are likely the target(s)?

The source code is an ocean. Just want to save a little bit my vision if an expert can point me a direction.

Thanks,

I mean since getting package version is probably 1/20 of RPM fucntions, it is no good to read through the whole RPM package.

I'd like to save a little bit time by looking into one (or several) particular files.

Thanks,

Does the API not have a function that, given the name of a package, will return the version of that package?
