The

.Ux
|
|
manuals and indexes them in a
|
|
.Sx Keyword Database
|
|
and
|
|
.Sx Index Database
|
|
for fast retrieval by

If fatal parse errors are encountered while parsing, the offending file
|
|
is printed to stderr, omitted from the index, and the parse continues
|

.Ss Index Database
|
|
The index database,

.Ss Keyword Database
|
|
The keyword database,

|
.Pa whatis.db ,
|
|
is a
|
|
.Xr btree 3
|
|
database of NUL-terminated keywords (record length is non-zero string
|
|
length plus one) mapping to a 16-byte binary field consisting of the

|
64-bit keyword type and the 64-bit
|
|
.Sx Index Database
|
|
record number, both in network-byte order.
|
|
.Pp
|
|
The type bit-mask consists of the following

.Sh IMPLEMENTATION NOTES
|
|
The time to construct a new database pair grows linearly with the
|
|
number of keywords in the input files.
|
|
However, removing or updating entries with
|
|
.Fl u
|
|
or
|
|
.Fl d ,
|
|
respectively, grows as a multiple of the index length and input size.

.Sh EXIT STATUS
|
|
The
|
|
.Nm
|
|
utility exits with one of the following values:
|
|
.Pp
|
|
.Bl -tag -width Ds -compact
|
|
.It 0
|
|
No errors occurred.
|
|
.It 5
|
|
Invalid command line arguments were specified.
|
|
No input files have been read.
|
|
.It 6
|
|
An operating system error occurred, for example memory exhaustion or an
|
|
error accessing input files.
|
|
Such errors cause
|
|
.Nm
|
|
to exit at once, possibly in the middle of parsing or formatting a file.
|
|
The output databases are corrupt and should be removed.
|
|
.El
|
|
.Sh DIAGNOSTICS
|
|
If the following errors occur, the
|
|
.Nm
|
|
databases should be rebuilt.
|
|
.Bl -diag
|
|
.It "%s: Corrupt database"
|
|
The keyword database file indicated by
|
|
.Pa %s
|
|
is unreadable.
|
|
.It "%s: Corrupt index"
|
|
The index database file indicated by
|
|
.Pa %s
|
|
is unreadable.
|
|
.It "%s: Path too long"
|
|
The file
|
|
.Pa %s
|
|
is too long.
|
|
This usually indicates database corruption or invalid command-line
|
|
arguments.
