Thanks, Aia!
So, it seems, I did understand pretty correct.
That means, my unclear, acctualy, is to the logic.

What the reason to restrict new-line (the \r,\n) on line beginning in C/C++ ?!
I am about the '^[^\r\n\{]*' in the #5 part: there is no any restriction in C/C++ ot get any number of new-line that does not brake a word!

How that could be having '<anything>;' between <func_nm>(..<params>..) and the {...} - the function body?! - that I see by #4 and beginning #5 :
- [^\{;] *?(?:^[^\r\n\{]*;?
- especially, finished by ';'?! And up to 10 times?!

That RegEx is searching a function declaration in a C/C++ source.
How those regulation could be useful in that task?

OCAMLCP(1)						      General Commands Manual							OCAMLCP(1)

NAME
ocamlcp - The Objective Caml profiling compiler SYNOPSIS
ocamlcp [ ocamlc options ] [ -p flags ] filename ... DESCRIPTION
The ocamlcp command is a front-end to ocamlc(1) that instruments the source code, adding code to record how many times functions are called, branches of conditionals are taken, ... Execution of instrumented code produces an execution profile in the file ocamlprof.dump, which can be read using ocamlprof(1). ocamlcp accepts the same arguments and options as ocamlc(1). OPTIONS
In addition to the ocamlc(1) options, ocamlcp accepts the following option controlling the amount of profiling information: -p letters The letters indicate which parts of the program should be profiled: a all options f function calls : a count point is set at the beginning of each function body i if ... then ... else: count points are set in both then and else branches l 0 loops: a count point is set at the beginning of the loop body m match branches: a count point is set at the beginning of the body of each branch of a pattern-matching t try ... with branches: a count point is set at the beginning of the body of each branch of an exception catcher For instance, compiling with ocamlcp -pfilm profiles function calls, if ... then ... else ..., loops, and pattern matching. Calling ocamlcp(1) without the -p option defaults to -p fm meaning that only function calls and pattern matching are profiled. Note: due to the implementation of streams and stream patterns as syntactic sugar, it is hard to predict what parts of stream expressions and patterns will be profiled by a given flag. To profile a program with streams, we recommend using ocamlcp -p a. SEE ALSO
