.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.
|
|
|
|
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: If \fBuse_env(FALSE)\fR has been called, values for
|
|
\fBlines\fR and \fBcolumns\fR specified in \fBterminfo\fR are used.
|
|
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.
|
|
|
|
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
|
|
|
|
\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.
|
|
|
|
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:
|
|
|
|
\fBsetupterm((char *)0, 1, (int *)0);\fR,
|
|
|
|
which uses all the defaults and sends the output to \fBstdout\fR.
|
|
|
|
The \fBsetterm\fR routine is being replaced by \fBsetupterm\fR. The call:
|
|
|
|
\fBsetupterm(\fR\fIterm\fR\fB, 1, (int *)0)\fR
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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, does a setupterm, and then restores the bits.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
The \fBvidattr\fR routine is like the \fBvidputs\fR routine, except
|
|
that it outputs through \fBputchar\fR.
|
|
|
|
The \fBmvcur\fR routine provides low-level cursor motion. It takes
|
|
effect immediately (rather than at the next refresh).
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
The \fIcapname\fR for each capability is given in the table column entitled
|
|
\fIcapname\fR code in the capabilities section of \fBterminfo\fR(\*n).
|
|
|
|
\fBchar *boolnames\fR, \fB*boolcodes\fR, \fB*boolfnames\fR
|
|
|
|
\fBchar *numnames\fR, \fB*numcodes\fR, \fB*numfnames\fR
|
|
|
|
\fBchar *strnames\fR, \fB*strcodes\fR, \fB*strfnames\fR
|
|
|
|
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.
|
|
|
|
Routines that return pointers always return \fBNULL\fR on error.
|
|
.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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
In System V Release 4, the third argument of \fBtputs\fR has the type
|
|
\fBint (*putc)(char)\fR.
|
|
|
|
The XSI Curses standard prototypes \fBtparm\fR with a fixed number of parameters,
|
|
rather than a variable argument list.
