| duke@435 | 28 | * The following definitions, prototypes are from Solaris libproc.h. |
| duke@435 | 29 | * We used to use the copy of it from Solaris 8.0. But there are |
| duke@435 | 30 | * problems with that approach in building this library across Solaris |
| duke@435 | 31 | * versions. Solaris 10 has libproc.h in /usr/include. And libproc.h |
| duke@435 | 32 | * varies slightly across Solaris versions. On Solaris 9, we get |
| duke@435 | 33 | * 'sysret_t multiply defined' error. This is common minimum subset we |
| duke@435 | 34 | * really need from libproc.h. The libproc.h in the current dir has |
| duke@435 | 35 | * been left for reference and not used in build. |
