59 These low-level routines must be called by programs that have to deal
60 directly with the terminfo database to handle certain terminal capabil‐
61 ities, such as programming function keys. For all other functionality,
62 curses routines are more suitable and their use is recommended.
63
64
65 Initially, setupterm() should be called. Note that setupterm() is auto‐
66 matically called by initscr() and newterm(). This defines the set of
67 terminal-dependent variables (listed in terminfo(4)). The terminfo
68 variables lines and columns are initialized by setupterm() as follows:
69 If use_env(FALSE) has been called, values for lines and columns speci‐
70 fied in terminfo are used. Otherwise, if the environment variables
71 LINES and COLUMNS exist, their values are used. If these environment
72 variables do not exist and the program is running in a window, the cur‐
73 rent window size is used. Otherwise, if the environment variables do
74 not exist, the values for lines and columns specified in the terminfo
75 database are used.
76
77
78 The headers <curses.h> and <term.h> should be included (in this order)
79 to get the definitions for these strings, numbers, and flags. Parame‐
80 terized strings should be passed through tparm() to instantiate them.
81 All terminfo strings (including the output of tparm()) should be
82 printed with tputs() or putp(). Call the reset_shell_mode() routine to
83 restore the tty modes before exiting (see curs_kernel(3CURSES)). Pro‐
84 grams which use cursor addressing should output enter_ca_mode upon
85 startup and should output exit_ca_mode before exiting. Programs desir‐
86 ing shell escapes should call reset_shell_mode and output exit_ca_mode
87 before the shell is called and should output enter_ca_mode and call
88 reset_prog_mode after returning from the shell.
89
90
91 The setupterm() routine reads in the terminfo database, initializing
92 the terminfo structures, but does not set up the output virtualization
93 structures used by curses. The terminal type is the character string
94 term; if term is null, the environment variable TERM is used. All out‐
95 put is to file descriptor fildes which is initialized for output. If
96 errret is not null, then setupterm() returns OK or ERR and stores a
97 status value in the integer pointed to by errret. A status of 1 in
98 errret is normal, 0 means that the terminal could not be found, and −1
99 means that the terminfo database could not be found. If errret is null,
100 setupterm() prints an error message upon finding an error and exits.
101 Thus, the simplest call is:
102
103
104 setupterm((char *)0, 1, (int *)0);,
105
106
107 which uses all the defaults and sends the output to stdout.
108
109
110 The setterm() routine is being replaced by setupterm(). The call:
111
112
113 setupterm(term, 1, (int *)0)
114
115
116 provides the same functionality as setterm(term). The setterm() routine
117 is included here for compatibility and is supported at Level 2.
118
119
120 The set_curterm() routine sets the variable cur_term to nterm, and
121 makes all of the terminfo boolean, numeric, and string variables use
122 the values from nterm.
123
124
125 The del_curterm() routine frees the space pointed to by oterm and makes
126 it available for further use. If oterm is the same as cur_term, refer‐
127 ences to any of the terminfo boolean, numeric, and string variables
128 thereafter may refer to invalid memory locations until another
129 setupterm() has been called.
130
131
132 The restartterm() routine is similar to setupterm() and initscr(),
133 except that it is called after restoring memory to a previous state. It
134 assumes that the windows and the input and output options are the same
135 as when memory was saved, but the terminal type and baud rate may be
136 different.
137
138
139 The tparm() routine instantiates the string str with parameters pi. A
140 pointer is returned to the result of str with the parameters applied.
141
142
143 The tputs() routine applies padding information to the string str and
144 outputs it. The str must be a terminfo string variable or the return
145 value from tparm(), tgetstr(), or tgoto(). affcnt is the number of
146 lines affected, or 1 if not applicable. putc is a putchar()-like rou‐
147 tine to which the characters are passed, one at a time.
148
149
150 The putp() routine calls tputs(str, 1, putchar). Note that the output
151 of putpA() always goes to stdout, not to the fildes specified in
152 setupterm().
153
154
155 The vidputs() routine displays the string on the terminal in the video
156 attribute mode attrs, which is any combination of the attributes listed
157 in curses(3CURSES). The characters are passed to the putchar()-like
158 routine putc() .
159
160
161 The vidattr() routine is like the vidputs() routine, except that it
162 outputs through putchar().
163
164
165 The mvcur() routine provides low-level cursor motion.
166
167
168 The tigetflag(), tigetnum() and tigetstr() routines return the value of
169 the capability corresponding to the terminfo capname passed to them,
170 such as xenl.
171
172
173 With the tigetflag() routine, the value −1 is returned if capname is
174 not a boolean capability.
175
176
177 With the tigetnum() routine, the value −2 is returned if capname is not
178 a numeric capability.
179
180
181 With the tigetstr() routine, the value (char *)−1 is returned if cap‐
182 name is not a string capability.
183
184
185 The capname for each capability is given in the table column entitled
186 capname code in the capabilities section of terminfo(4).
187
188 char *boolnames, *boolcodes, *boolfnames
189 char *numnames, *numcodes, *numfnames
190 char *strnames, *strcodes, *strfnames
191
192
193
194 These null-terminated arrays contain the capnames, the termcap codes,
195 and the full C names, for each of the terminfo variables.
196
198 All routines return the integer ERR upon failure and an integer value
199 other than ERR upon successful completion, unless otherwise noted in
200 the preceding routine descriptions.
201
202
203 Routines that return pointers always return NULL on error.
