I am currently trying to understand the C source of mysql-ruby.
there is a line at mysql.c which looks like this (line 40)
#define GetHandler(obj) (Check_Type(obj, T_DATA), &(((
and I do not understand what’s going on here.
what is this T_DATA
I couldn’t find anything in the pickaxe book and in README.EXT
there is only
in section 1.1 Data-types
can anybody explain me, what T_DATA is good for?
