SP, acs_map, boolcodes, boolfnames, boolnames, cur_term, numcodes, numfnames, numnames, strcodes, strfnames, strnames, ttytype - curses terminfo global variables SYNOPSIS
#include <curses.h> #include <term.h> chtype acs_map[]; NCURSES_CONST char * const * boolcodes; NCURSES_CONST char * const * boolfnames; NCURSES_CONST char * const * boolnames; TERMINAL * cur_term; NCURSES_CONST char * const * numcodes; NCURSES_CONST char * const * numfnames; NCURSES_CONST char * const * numnames; NCURSES_CONST char * const * strcodes; NCURSES_CONST char * const * strfnames; NCURSES_CONST char * const * strnames; char ttytype[]; DESCRIPTION
This page summarizes variables provided by the curses library's low-level terminfo interface. A more complete description is given in the curs_terminfo(3X) manual page. Depending on the configuration, these may be actual variables, or macros (see threads(3NCURSES)) which provide read-only access to curses's state. In either case, applications should treat them as read-only to avoid confusing the library. Alternate Character Set Mapping After initializing the curses or terminfo interfaces, the acs_map array holds information used to translate cells with the A_ALTCHARSET video attribute into line-drawing characters. The encoding of the information in this array has changed periodically. Application developers need only know that it is used for the "ACS_" constants in <curses.h>. The comparable data for the wide-character library is a private variable. Current Terminal Data After initializing the curses or terminfo interfaces, the cur_term contains data describing the current terminal. This variable is also set as a side-effect of set_term(3X) and delscreen(3X). It is possible to save a value of cur_term for subsequent use as a parameter to set_term, for switching between screens. Alternatively, one can save the return value from newterm or setupterm to reuse in set_term. Terminfo Names The tic(1) and infocmp(1) programs use lookup tables for the long and short names of terminfo capabilities, as well as the corresponding names for termcap capabilities. These are available to other applications, though the hash-tables are not available. The long terminfo capability names use a "l" (ell) in their names: boolfnames numfnames strfnames These are the short names for terminfo capabilities: boolnames, numnames, and strnames. These are the corresponding names used for termcap descriptions: boolcodes, numcodes, and strcodes. Terminal Type On initialization of the curses or terminfo interfaces, setupterm copies the terminal name to the array ttytype. NOTES
The low-level terminfo interface is initialized using setupterm(3X). The upper-level curses interface uses the low-level terminfo inter- face, internally. PORTABILITY
X/Open Curses does not describe any of these except for cur_term. (The inclusion of cur_term appears to be an oversight, since other com- parable low-level information is omitted by X/Open). Other implementations may have comparable variables. Some implementations provide the variables in their libraries, but omit them from the header files. SEE ALSO
