| 35 | These functions are not called directly - they're the targets of code |
| 36 | redirection or load notifications (see pub_core_redir.h for info). |
| 37 | They're named weirdly so that the intercept code can find them when the |
| 38 | shared object is initially loaded. |
| 39 | |
| 40 | Note that this filename has the "vg_" prefix because it can appear |
| 41 | in stack traces, and the "vg_" makes it a little clearer that it |
| 42 | originates from Valgrind. |
