(OFoldStream manipulator)
manpagename(FBB::mlm)(Manipulator modifying left margins of OFoldStream
objects)
manpagesynopsis()
bf(#include <bobcat/ofoldstream>) or nl()

Linking option: tt(-lbobcat)
manpagedescription()
The tt(mlm) class implements a manipulator that can be inserted into
tt(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 tt(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 tt(std::flush)
or tt(std::endl) manipulator that is inserted into the stream. If a line is
still empty once an tt(mlm) object and a tt(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 em(bad_cast) exception is thrown when the manipulator is inserted into an
tt(ostream) that is not using a tt(OFoldStreambuf) buffer.
