7 | /*this file, if included instead of <stdio.h> has the following functionality:
|
---|
8 | 1) if GB_TIME_INTERCEPT is defined then
|
---|
9 | a) some of the time.h symbols shall be redefined, for example: time => gb_time
|
---|
10 | b) all "code" using the time will actually (because of the preprocessor) call to gb_time
|
---|
11 | c) gb_time shall blindly call into time, thus realizing a passthrough
|
---|
12 |
|
---|
13 | reason is: unittesting. time comes with the C Run Time and cannot be mocked (that is, in the global namespace cannot exist a function called time
|
---|
14 |
|
---|
15 | 2) if GB_TIME_INTERCEPT is not defined then
|
---|
16 | a) it shall include <time.h> => no passthrough, just direct linking.
