NAME

ccaappmmkkddbb - create capability database

SYNOPSIS

ccaappmmkkddbb [-vv] [-ff outfile] file1 [file2 ...]

DESCRIPTION

CCaappmmkkddbb 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 as as follows:

-ff outfile

Specify a different database basename.

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

FFOORRMMAATT 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 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 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. RREETTUURRNN VVAALLUUEE The ccaappmmkkddbb utility exits 0 on success and >0 if an error occurs.
