FBB::lm(3bobcat)
OFoldStream manipulator
(libbobcat-dev_6.06.02)

NAME
FBB::lm - Manipulator setting left margins of OFoldStream objects
SYNOPSIS
    #include <bobcat/ofoldstream> or 
    #include <bobcat/ofoldbuf> 
    Linking option: -lbobcat
DESCRIPTION
The lm class implements a manipulator that can be inserted into
OFoldStream objects to set the stream's left margin to a requested
value.
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 used for 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 once an lm 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 OFoldBuf buffer.
NAMESPACE
    FBB
    All constructors, members, operators and manipulators, mentioned in this
man-page, are defined in the namespace FBB.
INHERITS FROM
    -
CONSTRUCTOR
    
Copy and move constructors (and assignment operators) are available.
MEMBER FUNCTIONS
    -  std::ostream &modify(std::ostream &out) const:
 This member is normally not directly called from
user-programs. Instead, it is called by the insertion operator when inserting
the lm manipulator.
EXAMPLE
        
    #include <iostream>
    #include <bobcat/ofoldstream>
    using namespace std;
    using namespace FBB;
    int main()
    {
        OFoldStream out(cout, 0, 80);
        out << "hello world (left margin is 0)" << lm(4) << "\n"
               "this uses a 4 character wide left margin\n" <<
               lm(0) << flush << "at column 0 again\n";
    }
