cap_mkdb - create capability database
cap_mkdb [-i] [-v] [-f outfile] file1 [file2 ...]
cap_mkdb builds a hashed database out of the getcap(3) or
terminfo(5)
logical database constructed by the concatenation of the
specified files.
The database is named by the basename of the first file argument and the
string ``.db''. The getcap(3) routines can access the
database in this
form much more quickly than they can the original text
file(s).
The ``tc'' capabilities of the records are expanded before
the record is
stored into the database.
The options are as follows:
-f outfile
Specify a different database basename.
-i Expect the capability records to be parsed to be in
terminfo(5)
format.
-v Print out the number of capability records in the
database.
Each record is stored in the database using two different
types of keys.
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.
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 first capability of the record. The
special byte is
a 2.
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.
The cap_mkdb utility exits 0 on success or >0 if an error
occurred.
