一个assert的写法

 1 char assert_buf[512];
 2 int assert_buf_len;
 3 
 4 #ifdef XXX_DEBUG
 5 #define assert(expr, ...) \
 6 do{    \
 7     if ((!(expr))) \
 8     {\
 9         char *str = __FILE__; \
10         int i; \
11         for(i=strlen(str);i>=0;i--) if(str[i]=='\\'||str[i]=='/') break; \
12         printf("ASSERTION FAILED (%s) at: %s:%d:: ", #expr, str+i+1, __LINE__);\
13         assert_buf_len = snprintf(assert_buf, sizeof(assert_buf)-1, __VA_ARGS__);\
14         printf("%s\r\n", assert_buf);\
15     }\
16 } while (0)
17 #else
18 #define assert(expr, ...) do{ \
19 }while(0)
