Brief

Sometimes, we need to use macro to complete some miracle task. In this lib, you can use those macro to operate macro parameters.

Basic function

list

func desp
GET_MACRO_PARAS_TOTAL_NUM(...) get count of macro paras.
GET_MACRO_PARA_N(N, ...) get macro para in order N.
GET_MACRO_PARAS_N_2_END(N, ...) get macro paras from order N to end.
GET_MACRO_PARAS_START_2_N(N, ...) get macro paras from order 0 to order N-1.
GET_MACRO_PARAS_N_2_M(N, M, ...) get macro paras from order N to order M-1.
GET_MACRO_PARAS_N_LEN(N, LEN, ...) get macro paras from order N to order N+LEN-1.
GET_MACRO_PARAS_RAM(N, ...) get N macro paras in ramdom order.
MACRO_PARAS_ENUM_OPT(opt, ...) provide 'opt' as a callback-func to every macro para.
MACRO_PARAS_ENUM_OPT_WITHOUT_LAST(opt, ...) provide opt as a callback-func to every macro para except the last one.
MACRO_PARAS_NOTDEAL_0PARAS(opt, ...) don't deal when macro paras is none.
