52: .Sh DESCRIPTION
1.6 aaron 53: .Nm cap_mkdb
1.1 deraadt 54: builds a hashed database out of the
55: .Xr getcap 3
1.7 ! tholo 56: or
! 57: .Xr terminfo 5
1.1 deraadt 58: logical database constructed by the concatenation of the specified
1.5 aaron 59: files.
1.1 deraadt 60: .Pp
61: The database is named by the basename of the first file argument and
62: the string
63: .Dq .db .
64: The
65: .Xr getcap 3
66: routines can access the database in this form much more quickly
67: than they can the original text file(s).
68: .Pp
69: The ``tc'' capabilities of the records are expanded before the
70: record is stored into the database.
71: .Pp
1.5 aaron 72: The options are as follows:
1.1 deraadt 73: .Bl -tag -width XXXXXX -indent
74: .It Fl f Ar outfile
75: Specify a different database basename.
1.7 ! tholo 76: .It Fl i
! 77: Expect the capability records to be parsed to be in
! 78: .Xr terminfo 5
! 79: format.
1.1 deraadt 80: .It Fl v
81: Print out the number of capability records in the database.
82: .El
83: .Pp
84: .Sh FORMAT
85: Each record is stored in the database using two different types of keys.
86: .Pp
87: The first type is a key which consists of the first capability of
1.6 aaron 88: the record (not including the trailing colon
89: .Pq Sq \&: )
90: with a data
1.1 deraadt 91: field consisting of a special byte followed by the rest of the record.
92: The special byte is either a 0 or 1, where a 0 means that the record
93: is okay, and a 1 means that there was a ``tc'' capability in the record
94: that couldn't be expanded.
95: .Pp
96: The second type is a key which consists of one of the names from the
97: first capability of the record with a data field consisting a special
1.3 deraadt 98: byte followed by the first capability of the record.
1.1 deraadt 99: The special byte is a 2.
100: .Pp
101: In normal operation names are looked up in the database, resulting
102: in a key/data pair of the second type.
103: The data field of this key/data pair is used to look up a key/data
104: pair of the first type which has the real data associated with the
105: name.
106: .Sh RETURN VALUE
107: The
108: .Nm cap_mkdb
1.6 aaron 109: utility exits 0 on success or >0 if an error occurred.
