RANLIB(1) General Commands Manual RANLIB(1)NAME
ranlib - table-of-contents for archive libraries
ranlib [-t] file ...
Ranlib creates a table of external references for archive libraries, normally used by the loader, ld(1). This table is is named
``__.SYMDEF'' and is prepended to the archive. Files in the archive which are not executable and symbols which are uninteresting to the
loader are ignored.
The options are as follows:
-t Set the modification time of the __.SYMDEF file. This time is compared by the loader with the modification time of the archive to
verify that the table is up-to-date with respect to the archive. If the modification time has been changed without any change to
the archive (for example, by a cp(1)), the -t option can be used to ``touch'' the modification time so that it appears that the ta-
ble is up-to-date.
/tmp default temporary file directory
ranlib.XXXXXX temporary file names

ranlib -- archive (library) table-of-contents format
The archive table-of-contents command ranlib creates a table of contents for archives, containing object files, to be used by the link-editor
ld(1). It operates on archives created with the utility ar(1).
The Ranlib function prepends a new file to the archive which has three separate parts. The first part is a standard archive header, which
has a special name field, "__.SYMDEF" or "__.SYMDEF SORTED". If the archive does not have multiple members that define symbol then
"__.SYMDEF SORTED" should be used and the table of contents should be sorted by name.
The second part is a ``long'' followed by a list of ranlib structures. The long is the size, in bytes, of the list of ranlib structures.
Each of the ranlib structures consists of a zero based offset into the next section (a string table of symbols) and an offset from the begin-
ning of the archive to the start of the archive file which defines the symbol. The actual number of ranlib structures is this number divided
by the size of an individual ranlib structure.
The third part is a ``long'' followed by a string table. The long is the size, in bytes of the string table.
