Accesing Databases

["Nicolas Raitman" <new_world radar com ar>]

Hi to all! I will develop a simple application, that will be like an
addressbook. I am having one big problem, I do not know the functions to
access to a mysql or postgresql database. I know those functions that work
with php and I also have a good unsertanding of databases and sql language,
so the only problem that I have is that I do not know the names of the
functions to access a database and also the data types returned by them. One
more thing... which other 'include' I will have to make? Can you give me a
hint?

One more thing... is there a special library to access databases with gtk+?

Thanks a lot,
Nicolas
