findpattern help

-----------------------------------

I want to build extended find pattern for modern warfare 2 for finding offsets... I have this code and "variable"_t make me a problem...I do not know how to make the prints as clientinfo, CG, CGS and centity every time I start the program...  refdef is static,does not change... clientinfo,cg,cgs and centity is change every time I start play...can anyone help me... :/
#include

int clientinfo_addy = -1;
int cg_addy = -1;

centity_t * cg_entities; // = (centity_t*) 0x8F7A78;
refdef_t * refdef = (refdef_t*) 0x85EFB0;
cg_t * cg; // = (cg_t*) 0x7F493C;
cgs_t * cgs; // = (cgs_t*) 0x7F0C78;
