OCAMLPROF(1) General Commands Manual OCAMLPROF(1)NAME
ocamlprof - The OCaml profiler
SYNOPSIS
ocamlprof [ options ] filename ...
DESCRIPTION
The ocamlprof command prints execution counts gathered during the execution of a OCaml program instrumented with ocamlcp(1).
It produces a source listing of the program modules given as arguments where execution counts have been inserted as comments. For instance,
ocamlprof foo.ml
prints the source code for the foo module, with comments indicating how many times the functions in this module have been called. Natu-
rally, this information is accurate only if the source file has not been modified since the profiling execution took place.
OPTIONS -f dumpfile
Specifies an alternate dump file of profiling information.
-F string
Specifies an additional string to be output with profiling information. By default, ocamlprof(1) will annotate programs with com-
ments of the form (* n *) where n is the counter value for a profiling point. With option -F s the annotation will be (* sn *)
-impl filename
Compile the file filename as an implementation file, even if its extension is not .ml.
-intf filename
Compile the file filename as an interface file, even if its extension is not .mli.
-version
Print version string and exit.
-vnum Print short version number and exit.
-help or --help
Display a short usage summary and exit.

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.

OCAMLCP(1)
Hello,
i am try to write a profiler for a multithreaded applciation. When i creat e a thread for "function f2()" the profiling information for this function does not get captured in the struct profileManager. i;e i get the exit information for "function f2()" in that thread, but the entry... (2 Replies)
question goes like this :
Explain how users can profile execution of a process with help of an example?
can some one pls give me the answer?? (1 Reply)
