.Sh DESCRIPTION
|
|
.Nm Cap_mkdb
|
|
builds a hashed database out of the
|
|
.Xr getcap 3
|
|
logical database constructed by the concatenation of the specified
|
|
files .
|
|
.Pp
|
|
The database is named by the basename of the first file argument and
|
|
the string
|
|
.Dq .db .
|
|
The
|
|
.Xr getcap 3
|
|
routines can access the database in this form much more quickly
|
|
than they can the original text file(s).
|
|
.Pp
|
|
The ``tc'' capabilities of the records are expanded before the
|
|
record is stored into the database.
|
|
.Pp
|
|
The options as as follows:
|
|
.Bl -tag -width XXXXXX -indent
|
|
.It Fl f Ar outfile
|
|
Specify a different database basename.
|
|
.It Fl v
|
|
Print out the number of capability records in the database.
|
|
.El
|
|
.Pp
|
|
.Sh FORMAT
|
|
Each record is stored in the database using two different types of keys.
|
|
.Pp
|
|
The first type is a key which consists of the first capability of
|
|
the record (not including the trailing colon (``:'')) with a data
|
|
field consisting of a special byte followed by the rest of the record.
|
|
The special byte is either a 0 or 1, where a 0 means that the record
|
|
is okay, and a 1 means that there was a ``tc'' capability in the record
|
|
that couldn't be expanded.
|
|
.Pp
|
|
The second type is a key which consists of one of the names from the
|
|
first capability of the record with a data field consisting a special
|
|
byte followed by the the first capability of the record.
|
|
The special byte is a 2.
|
|
.Pp
|
|
In normal operation names are looked up in the database, resulting
|
|
in a key/data pair of the second type.
|
|
The data field of this key/data pair is used to look up a key/data
|
|
pair of the first type which has the real data associated with the
|
|
name.
|
|
.Sh RETURN VALUE
|
|
The
|
|
.Nm cap_mkdb
|
|
utility exits 0 on success and >0 if an error occurs.
