| 3 | * Purpose: declaration of External Config stuff for omalloc |
|---|
| 4 | * This file is inlcuded by omDefaultConfig.h, i.e., at the the time |
|---|
| 5 | * the omalloc library is built. Any changes to the default config |
|---|
| 6 | * of omalloc should be done here (and, of course, you need to |
|---|
| 7 | * rebuilt the library). |
