about C program CPP macro
Hello, all:
I have a program problem, ( may it not have close releationship with Debian), it described like this:
I want to using #define / #undef, and want to put them in a single macro, some thing like:
#define DECALRE_TYPE(type) \
{ #undef __curr_type; #define _curr_type type; }
as we know, this can not passed with CPP, but I need this logical here.
Generally, the problem comes from
#define ser_field(type, var) \
ser_new_field(tra, #type, #var, offsetof(struct_type, var))
I do not want another additional parameter in this macro like
#define ser_field(type,var,struct_type), and I want a sentence declare "current struct type"
and all later work of ser_field will defaultly use this type.
I am not sure whether I can express it clearly, any ideas will be greately appreciated!
Thanks and B.R.
