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 FILES .Bl -tag -width Ds -.It Pa mandoc.db -A -.Xr btree 3 -keyword database mapping keywords to a type and file reference in -.Pa mandoc.index . -.It Pa

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

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. -.El +.Ex -std .Sh SEE ALSO +.Xr apropos 1 , .Xr man 1 , -.Xr btree 3 , -.Xr recno 3 +.Xr whatis 1 , +.Xr man.conf 5 .Sh AUTHORS The
