| 3 | * FreeBSD 5.3
|
|---|
| 4 | *
|
|---|
| 5 | * @changed Commented out stuff which isn't implemented, TCPIP stuff at bottom.
|
|---|
| 6 | * @changed setkey returns void not int in the standard and our implementation (glibc).
|
|---|
| 7 | * @todo Several man-years.. ;) Serious, complete the FreeBSD 5.3 merge and
|
|---|
| 8 | * implement all the functions. Currently there is a bunch of POSIX
|
|---|
| 9 | * #defines missing.
