CAP_MKDB(1)		FreeBSD	General	Commands Manual		   CAP_MKDB(1)

NAME
     cap_mkdb -- create	capability database

SYNOPSIS
     cap_mkdb [-b | -l]	[-v] [-f outfile] file ...

DESCRIPTION
     The cap_mkdb utility builds a hashed database out of the getcap(3)	logi-
     cal 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 following options are available:

     -b	     Use big-endian byte order for database metadata.

     -f	outfile
	     Specify a different database basename.

     -l	     Use little-endian byte order for database metadata.

     -v	     Print out the number of capability	records	in the database.

     The -b and	-l flags are mutually exclusive.  The default byte ordering is
     the current host order.

FORMAT
     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 con-
     sisting of	a special byte followed	by the rest of the record.  The	spe-
     cial 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 could
     not 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.

EXIT STATUS
     The cap_mkdb utility exits	0 on success, and >0 if	an error occurs.
