| // This header plugs in the leaks of stdio functions called as std::<function> |
| // and __builtin_<function>. |
| |
| // IMPORTANT: This header has to be included as the very first header in a file, |
| // because the order of the included headers and redefininitions matter. |
| |
| // In this header, it includes <cstdio> at the very beginning, so that the |
| // attempts to include <cstdio> afterward are omitted. Then we define a function |
| // in the std namespace that has the name of the Starboard counterpart of the |
| // function to be plugged, and redirect it to the Starboard counterpart in the |
| // global namespace. In this way, the calls to std::<function> will be replaced |
| // with std::<SbConterpart>, and redirected to ::<SbCounterpart>. With this |
| // specific order of included headers and redefininitions, it's guaranteed that |
| // the calls of the functions afterward are cleanly plugged. |
