The
.ft B
mtext_line_break()
.ft R
function checks if position
.ft B
pos
.ft R
is a proper linebreak position of an M-text
.ft B
mt
.ft R
according to the algorithm of The Unicode Standard 4.0 UAX#14. It so, it returns
.ft B
pos\fP.
.ft R
Otherwise, it returns a proper linebreak position before
.ft B
pos\fP.
.ft R
.PP
If
.ft B
option
.ft R
is nonzero, it controls the algorithm by logical-or of the members of
.ft B
MTextLineBreakOption\fP.

after
.ft R
is not NULL, a proper linebreak position after
