Not exaclty (sorry I have been on vacation, not sure if this has been
addressed it... but that is the exact error message that is returned by
error #1.
The differenec in the socvket structer between BSD and SysV is as follow:
BSD:
struct {
word family;
...
} ;
SysV:
struct {
u_char size;
u_char family
}
for AF_INET the size is always 0x10 (16 dec). I am not sure how/if this
should be fixed in FreeBSD, but that is the cause of the error.
