The section initialization routine (_INITSCT), provided as the standard library, operates similarly
to the program shown below.
static const struct DSEC{
};
static const struct BSEC{
};
static void clearblock(void *b_top, void *b_end);
static void copyblock (void *d_top, void *d_end, void *r_top);
#ifdef _ _cplusplus
extern “c”
