看這個真頭大:P 還好gcc能幫忙


qrtt1@debian:~/test$ gcc -E orz.c 
# 1 &quot;orz.c&quot; 
# 1 &quot;&lt;built-in&gt;&quot; 
# 1 &quot;&lt;command line&gt;&quot; 
# 1 &quot;orz.c&quot; 
typedef enum { TYPE_UNSET, TYPE_STRING, TYPE_COUNT, TYPE_ARRAY, TYPE_INTEGER, TYPE_FASTCGI, TYPE_CONFIG } data_type_t; 
# 12 &quot;orz.c&quot; 
typedef struct data_unset { 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; data_type_t type; buffer *key; int is_index_key; struct data_unset *(*copy)(const struct data_unset *src); void (* free)(struct data_unset *p); void (* reset)(struct data_unset *p); int (*insert_dup)(struct data_unset *dst, struct data_unset *src); void (*print)(const struct data_unset *p, int depth);
