If the record value is zero-length, it is unassigned. |
|
.Ss Keyword Database |
|
The keyword database, |

|
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 |

.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 |

|
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. |
