NetBSD 6.1.5 - man page for cap_mkdb (netbsd section 1)

CAP_MKDB(1)			   BSD General Commands Manual			      CAP_MKDB(1)

NAME
     cap_mkdb -- create capability database

SYNOPSIS
     cap_mkdb [-b | -l] [-v] [-f outfile] file1 [file2 ...]

DESCRIPTION
     cap_mkdb builds a hashed database out of the getcap(3) 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:

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

FORMAT
     The following is a description of the hashed database created by cap_mkdb.  For a descrip-
     tion of the format of the input files see termcap(5).

     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.

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