代码有些复杂对C的宏定义需要非常熟悉

 1 #define PRINT_STAT(NAME,PRIMARY,SECONDARY,UNITS,TYPE) \
 2 do { \
 3   printf ("c %-" SFW1 "s %"  SFW2 PRIu64 " ", NAME ":", (uint64_t) PRIMARY); \
 4   const double SAVED_SECONDARY = (double) (SECONDARY); \
 5   const char * SAVED_UNITS = (const char*) (UNITS); \
 6   const char * SAVED_TYPE = (const char *) (TYPE); \
 7   if (SAVED_TYPE && SAVED_SECONDARY >= 0) \
 8     { \
 9       if (SAVED_UNITS) \
10     printf ("%" SFW34 ".0f %-2s", SAVED_SECONDARY, SAVED_UNITS); \
11       else \
12     printf ("%" SFW34EXTENDED ".2f", SAVED_SECONDARY); \
13       fputc (' ', stdout); \
14       fputs (SAVED_TYPE, stdout); \
15     } \
