|
|
.Nd "trim the current domain name from a host name"
|

.Sh SYNOPSIS
|
|
.Fd #include <sys/types.h>
|
|
.Fd #include <libutil.h>
|
|
.Ft void
|
|
.Fn trimdomain "char *fullhost" "int hostsize"
|
|
.Sh DESCRIPTION
|
|
The function
|
|
.Fn trimdomain
|
|
removes the current domain name from the passed
|
|
.Ar fullhost
|
|
name by writing a
|
|
.Dv NUL
|
|
character over the first period of the passed name. The current domain
|
|
name is determined by calling
|
|
.Xr gethostname 3
|
|
and removing everything up to the first period. The name is determined
|
|
the first time this function is called and is cached for future use.
|
|
.Pp
|
|
.Fn trimdomain
|
|
will only trim the domain name if the passed
|
|
.Ar fullname
|
|
ends with the current domain name and if the length of the resulting host
|
|
name does not exceed
|
|
.Ar hostsize .
|
|
.Pp
|
|
If the passed
|
|
.Ar fullname
|
|
is actually a

|
.Ar host No . Ar domain No : Ns
|
|
.Sm on
|
|
.Ar \&nn Oo
|
|
.No . Ns Ar \&nn
|
|
.Oc
|
|
and the domain name is the same as the local domain name,
|
|
.Fn trimdomain
|
|
will remove the embedded domain name, copying the screen and display
|
|
numbers to the end of the base host name and resulting in
|
|
.Ar host No : Ns Ar \&nn Oo
|
|
.No . Ns Ar \&nn
