They were not supported on +Version 7, BSD or System V implementations. It is recommended that +any code depending on them be conditioned using NCURSES_VERSION. +.. +.SH SEE ALSO +\fBcurs_color\fR(3X), +\fBded\fP(1). +.. +.SH AUTHOR +Thomas Dickey (from an analysis of the requirements for color xterm +for XFree86 3.1.2C, February 1996). +.\"# +.\"# The following sets edit modes for GNU EMACS +.\"# Local Variables: +.\"# mode:nroff +.\"# fill-column:79 +.\"# End: |
