-.SH DESCRIPTION
-These low-level routines must be called by programs that have to deal
-directly with the \fBterminfo\fR database to handle certain terminal
-capabilities, such as programming function keys.  For all other
-functionality, \fBcurses\fR routines are more suitable and their use is
-recommended.
-.PP
-Initially, \fBsetupterm\fR should be called.  Note that
-\fBsetupterm\fR is automatically called by \fBinitscr\fR and
-\fBnewterm\fR.  This defines the set of terminal-dependent variables
-[listed in \fBterminfo\fR(\*n)].
-The \fBterminfo\fR variables
-\fBlines\fR and \fBcolumns\fR are initialized by \fBsetupterm\fR as
-follows:
-.RS
-.PP
-If \fBuse_env(FALSE)\fR has been called, values for
-\fBlines\fR and \fBcolumns\fR specified in \fBterminfo\fR are used.
-.PP
-Otherwise, if the environment variables \fBLINES\fR and \fBCOLUMNS\fR
-exist, their values are used.  If these environment variables do not
-exist and the program is running in a window, the current window size
-is used.  Otherwise, if the environment variables do not exist, the
-values for \fBlines\fR and \fBcolumns\fR specified in the
-\fBterminfo\fR database are used.
-.RE
-.PP
-The header files \fBcurses.h\fR and \fBterm.h\fR should be included (in this
-order) to get the definitions for these strings, numbers, and flags.
-Parameterized strings should be passed through \fBtparm\fR to instantiate them. 
-All \fBterminfo\fR strings [including the output of \fBtparm\fR] should be printed
-with \fBtputs\fR or \fBputp\fR.  Call the \fBreset_shell_mode\fR to restore the
-tty modes before exiting [see \fBcurs_kernel\fR(3X)].  Programs which use
-cursor addressing should output \fBenter_ca_mode\fR upon startup and should
-output \fBexit_ca_mode\fR before exiting.  Programs desiring shell escapes
-should call
-.PP
-\fBreset_shell_mode\fR and output \fBexit_ca_mode\fR before the shell
-is called and should output \fBenter_ca_mode\fR and call
-\fBreset_prog_mode\fR after returning from the shell.
-.PP
-The \fBsetupterm\fR routine reads in the \fBterminfo\fR database,
-initializing the \fBterminfo\fR structures, but does not set up the
-output virtualization structures used by \fBcurses\fR.  The terminal
-type is the character string \fIterm\fR; if \fIterm\fR is null, the
-environment variable \fBTERM\fR is used.
-All output is to file descriptor \fBfildes\fR which is initialized for output.
-If \fIerrret\fR is not null,
-then \fBsetupterm\fR returns \fBOK\fR or
-\fBERR\fR and stores a status value in the integer pointed to by
-\fIerrret\fR.
-A return value of \fBOK\fR combined with status of \fB1\fR in \fIerrret\fR
-is normal.
-If \fBERR\fR is returned, examine \fIerrret\fR:
-.RS
-.TP 5
-.B 1
-means that the terminal is hardcopy, cannot be used for curses applications.
-.TP 5
-.B 0
-means that the terminal could not be found,
-or that it is a generic type,
-having too little information for curses applications to run.
-.TP 5
-.B -1
-means that the \fBterminfo\fR database could not be found.
-.RE
-.PP
-If \fIerrret\fR is
-null, \fBsetupterm\fR prints an error message upon finding an error
-and exits.  Thus, the simplest call is:
-.sp
-      \fBsetupterm((char *)0, 1, (int *)0);\fR,
-.sp
-which uses all the defaults and sends the output to \fBstdout\fR.
-.PP
-The \fBsetterm\fR routine is being replaced by \fBsetupterm\fR.  The call:
-.sp
-      \fBsetupterm(\fR\fIterm\fR\fB, 1, (int *)0)\fR
-.sp
-provides the same functionality as \fBsetterm(\fR\fIterm\fR\fB)\fR.
-The \fBsetterm\fR routine is included here for BSD compatibility, and
-is not recommended for new programs.
-.PP
-The \fBset_curterm\fR routine sets the variable \fBcur_term\fR to
-\fInterm\fR, and makes all of the \fBterminfo\fR boolean, numeric, and
-string variables use the values from \fInterm\fR.  It returns the old value
-of \fBcur_term\fR.
-.PP
-The \fBdel_curterm\fR routine frees the space pointed to by
-\fIoterm\fR and makes it available for further use.  If \fIoterm\fR is
-the same as \fBcur_term\fR, references to any of the \fBterminfo\fR
-boolean, numeric, and string variables thereafter may refer to invalid
-memory locations until another \fBsetupterm\fR has been called.
-.PP
-The \fBrestartterm\fR routine is similar to \fBsetupterm\fR and \fBinitscr\fR,
-except that it is called after restoring memory to a previous state (for
-example, when reloading a game saved as a core image dump).  It assumes that
-the windows and the input and output options are the same as when memory was
-saved, but the terminal type and baud rate may be different.  Accordingly,
-it saves various tty state bits, calls \fBsetupterm\fP,
-and then restores the bits.
-.PP
-The \fBtparm\fR routine instantiates the string \fIstr\fR with
-parameters \fIpi\fR.  A pointer is returned to the result of \fIstr\fR
-with the parameters applied.
-.PP
-The \fBtputs\fR routine applies padding information to the string
-\fIstr\fR and outputs it.  The \fIstr\fR must be a terminfo string
-variable or the return value from \fBtparm\fR, \fBtgetstr\fR, or
-\fBtgoto\fR.  \fIaffcnt\fR is the number of lines affected, or 1 if
-not applicable.  \fIputc\fR is a \fBputchar\fR-like routine to which
-the characters are passed, one at a time.
-.PP
-The \fBputp\fR routine calls \fBtputs(\fR\fIstr\fR\fB, 1, putchar)\fR.
-Note that the output of \fBputp\fR always goes to \fBstdout\fR, not to
-the \fIfildes\fR specified in \fBsetupterm\fR.
-.PP
-The \fBvidputs\fR routine displays the string on the terminal in the
-video attribute mode \fIattrs\fR, which is any combination of the
-attributes listed in \fBcurses\fR(3X).  The characters are passed to
-the \fBputchar\fR-like routine \fIputc\fR.
-.PP
-The \fBvidattr\fR routine is like the \fBvidputs\fR routine, except
-that it outputs through \fBputchar\fR.
-.PP
-The \fBvid_attr\fR and \fBvid_puts\fR routines correspond to vidattr and vidputs,
-respectively.
-They use a set of arguments for representing the video attributes plus color,
-i.e.,
-one of type attr_t for the attributes and one of short for
-the color_pair number.
-The \fBvid_attr\fR and \fBvid_puts\fR routines
-are designed to use the attribute constants with the \fIWA_\fR prefix.
-The opts argument is reserved for future use.
-Currently, applications must provide a null pointer for that argument.
-.PP
-The \fBmvcur\fR routine provides low-level cursor motion.  It takes
-effect immediately (rather than at the next refresh).
-.PP
-The \fBtigetflag\fR, \fBtigetnum\fR and \fBtigetstr\fR routines return
-the value of the capability corresponding to the \fBterminfo\fR
-\fIcapname\fR passed to them, such as \fBxenl\fR.
-.PP
-The \fBtigetflag\fR routine returns the value \fB-1\fR if
-\fIcapname\fR is not a boolean capability,
-or \fB0\fR if it is canceled or absent from the terminal description.
-.PP
-The \fBtigetnum\fR routine returns the value \fB-2\fR if
-\fIcapname\fR is not a numeric capability,
-or \fB-1\fR if it is canceled or absent from the terminal description.
-.PP
-The \fBtigetstr\fR routine returns the value \fB(char *)-1\fR
-if \fIcapname\fR is not a string capability,
-or \fB0\fR if it is canceled or absent from the terminal description.
-.PP
-The \fIcapname\fR for each capability is given in the table column entitled
-\fIcapname\fR code in the capabilities section of \fBterminfo\fR(\*n).

-.RE
-.PP
-These null-terminated arrays contain the \fIcapnames\fR, the
-\fBtermcap\fR codes, and the full C names, for each of the
-\fBterminfo\fR variables.
-.SH RETURN VALUE
-Routines that return an integer return \fBERR\fR upon failure and \fBOK\fR
-(SVr4 only specifies "an integer value other than \fBERR\fR") upon successful
-completion, unless otherwise noted in the preceding routine descriptions.
-.PP
-Routines that return pointers always return \fBNULL\fR on error.
-.PP
-X/Open defines no error conditions.
-In this implementation
-.RS
-.TP 5
-\fBdel_curterm\fP
-returns an error
-if its terminal parameter is null.
-.TP 5
-\fBrestartterm\fP
-returns an error
-if the associated call to \fBsetupterm\fP returns an error.
-.TP 5
-\fBsetupterm\fP
-returns an error
-if it cannot allocate enough memory, or
-create the initial windows (stdscr, curscr, newscr).
-Other error conditions are documented above.
-.RE
-.SH NOTES
-The \fBsetupterm\fR routine should be used in place of \fBsetterm\fR.
-It may be useful when you want to test for terminal capabilities without
-committing to the allocation of storage involved in \fBinitscr\fR.
-.PP
-Note that \fBvidattr\fR and \fBvidputs\fR may be macros.
-.SH PORTABILITY
-The function \fBsetterm\fR is not described in the XSI Curses standard and must
-be considered non-portable.  All other functions are as described in the XSI
-curses standard.
-.PP
-\fBsetupterm\fP copies the terminal name to the array \fBttytype\fP.
-This is not part of X/Open Curses, but is assumed by some applications.
-.PP
-In System V Release 4, \fBset_curterm\fR has an \fBint\fR return type and
-returns \fBOK\fR or \fBERR\fR.  We have chosen to implement the XSI Curses
-semantics.
-.PP
-In System V Release 4, the third argument of \fBtputs\fR has the type
-\fBint (*putc)(char)\fR.
-.PP
-The XSI Curses standard prototypes \fBtparm\fR with a fixed number of parameters,
-rather than a variable argument list.
-This implementation uses a variable argument list.
-Portable applications should provide 9 parameters after the format;
-zeroes are fine for this purpose.
-.PP
-XSI notes that after calling \fBmvcur\fR, the curses state may not match the
-actual terminal state, and that an application should touch and refresh
-the window before resuming normal curses calls.
-Both ncurses and System V Release 4 curses implement \fBmvcur\fR using
-the SCREEN data allocated in either \fBinitscr\fR or \fBnewterm\fR.
-So though it is documented as a terminfo function,
-\fBmvcur\fR is really a curses function which is not well specified.
-.PP
-XSI states that the old location must be given for \fBmvcur\fP.
-This implementation allows the caller to use -1's for the old ordinates.
-In that case, the old location is unknown.
-.PP
-Extended terminal capability names, e.g., as defined by \fBtic\ -x\fP,
-are not stored in the arrays described in this section.
