- iiddeenntt [ --qq ] [ _f_i_l_e ... ]
-
- DDEESSCCRRIIPPTTIIOONN
- iiddeenntt searches for all occurrences of the pattern
- $$_k_e_y_w_o_r_d::_._._.$$ in the named files or, if no files are
- named, the standard input.
-
- These patterns are normally inserted automatically by the
- RCS command ccoo(1), but can also be inserted manually. The
- option --qq suppresses the warning given if there are no
- patterns in a file.
-
- iiddeenntt works on text files as well as object files and
- dumps. For example, if the C program in ff..cc contains
-
- ##iinncclluuddee <<ssttddiioo..hh>>
- ssttaattiicc cchhaarr ccoonnsstt rrccssiidd[[]] ==
- ""$$IIdd:: ff..cc,,vv 55..22 11999922//0077//2288 1166::1122::4444 eeggggeerrtt EExxpp
- $$"";;
- iinntt mmaaiinn(()) {{ rreettuurrnn pprriinnttff((""%%ss\\nn"",, rrccssiidd)) ==== EEOOFF;; }}
-
- and ff..cc is compiled into ff..oo, then the command
-
- iiddeenntt ff..cc ff..oo
-
- will output
-
- ff..cc::
- $$IIdd:: ff..cc,,vv 55..22 11999922//0077//2288 1166::1122::4444 eeggggeerrtt EExxpp $$
- ff..oo::
- $$IIdd:: ff..cc,,vv 55..22 11999922//0077//2288 1166::1122::4444 eeggggeerrtt EExxpp $$
-
- See ccoo(1) for the list of keywords that it maintains.
- iiddeenntt finds all instances of patterns that look like
- keyword strings, even if they are not actually keywords.
- This gives you information about nonstandard keywords like
- $$XXCCoonnssoorrttiiuumm$$.
-
- If a C program defines a string like rrccssiidd above but does
- not use it, lliinntt(1) may complain, and some C compilers
- will optimize away the string. The most reliable solution
- is to have the program use the rrccssiidd string, as shown in
- the example above.
