Thanks for pointing that.
OK we found out a way that the above issue could be possible code wise. Its the hierarchy of how we are linking our binary is the issue. Let me explain the situation - we have one header file that is conditionally compiled with #ifndef .. #define .. #endif kept in different directory. Now this header files gets archived into lib1.a lib2.a and so on. Hence when we link our library and if incase we required it from lib3.a during linking we need to make sure that it linked the first:
ldd .. lib1.a lib2.a lib3.a -- so the exact header does not gets linked properly. Note that all .a have some additional interfaces compiled and linked.
Its unfortunate is that the required header contains common declaration (defines same methods but are little bit different)
How can we resolve the issue? Including Namespace would mean a lot of revamp in our codebase? Is there a better way to do that?
What would be best design for such a code base - so that later onwards no developer can accidentally include these fatal signatures?
Please help

is there any recommendation, especially from a point of performance, about where to place a user-defined function in awk, like in BEGIN{} or if it is only need once at the end in END{}? Or doesn't it matter at all since, awk is so clever and only interprets it once, wherever it is... (3 Replies)

FBB::mlm(3bobcat) OFoldStream manipulator FBB::mlm(3bobcat)
NAME
FBB::mlm - Manipulator modifying left margins of OFoldStream objects
SYNOPSIS
#include <bobcat/ofoldstream> or
#include <bobcat/ofoldstreambuf>
Linking option: -lbobcat
DESCRIPTION
The mlm class implements a manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the request
then left margin 0 will silently be used.
Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of
tab-characters that will be added to the left margin.
The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a
line is still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
the next word inserted into that line (cf., the example section below)
A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.
NAMESPACE
FBB
All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.

out << "hello world (left margin is 0)" << mlm(4) << "
"
"this uses a 4 character wide left margin
" <<
mlm(-10) << flush <<
"left margin -6 changed to 0, active on this line
";
return 0;
