+.SH DESCRIPTION
+This page summarizes variables provided by the \fBcurses\fP library's
+low-level terminfo interface.
+A more complete description is given in the \fBcurs_terminfo\fP(3X) manual page.
+.PP
+Depending on the configuration, these may be actual variables,
+or macros (see \fBcurs_threads\fP(3X))
+which provide read-only access to \fIcurses\fP's state.
+In either case, applications should treat them as read-only to avoid
+confusing the library.
+.SS "Alternate Character Set Mapping"
+After initializing the curses or terminfo interfaces,
+the \fBacs_map\fP array holds information used to translate cells
+with the \fBA_ALTCHARSET\fP video attribute into line-drawing characters.
+.PP
+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>.
+.PP
+The comparable data for the wide-character library is a private variable.
+.SS "Current Terminal Data"
+After initializing the curses or terminfo interfaces,
+the \fBcur_term\fP contains data describing the current terminal.
+This variable is also set as a side-effect of \fBset_term\fP(3X)
+and \fBdelscreen\fP(3X).
+.PP
+It is possible to save a value of \fBcur_term\fP for subsequent
+use as a parameter to \fBset_term\fP, for switching between screens.
+Alternatively, one can save the return value from \fBnewterm\fP
+or \fBsetupterm\fP(3X) to reuse in \fBset_term\fP.
+.SS "\fIterminfo\fP Lookup Tables"
+The \fBtic\fP(1) and \fBinfocmp\fP(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,
+although the hash-tables used by
+the terminfo and termcap functions are not available.
+.PP
+The long terminfo capability names use a \*(``f\*('' (eff) in their names:
+\fBboolfnames\fP,
+\fBnumfnames\fP, and
+\fBstrfnames\fP.
+.PP
+These are the short names for terminfo capabilities:
+\fBboolnames\fP,
+\fBnumnames\fP, and
+\fBstrnames\fP.
+.PP
+These are the corresponding names used for termcap descriptions:
+\fBboolcodes\fP,
+\fBnumcodes\fP, and
+\fBstrcodes\fP.
+.\"
+.SS "Terminal Type"
+A terminal description begins with one or more terminal names
+separated by \*(``|\*('' (vertical bars).
+On initialization of the curses or terminfo interfaces,
+\fBsetupterm\fP(3X) copies the terminal names to the array \fBttytype\fP.
+.\"
+.SS "\fIterminfo\fP Names"
+In addition to the variables, \fB<term.h>\fP also defines a symbol for each
+terminfo capability \fIlong name\fP.
+These are in terms of the symbol \fBCUR\fP,
+which is defined
+.PP
+.EX
+#define CUR ((TERMTYPE *)(cur_term))\->
+.EE
+.PP
+These symbols provide a faster method of accessing terminfo capabilities
+than using \fBtigetstr\fP(3X), etc.
+.PP
+The actual definition of \fBCUR\fP depends upon the implementation,
+but each terminfo library provides these long names defined to point
+into the current terminal description loaded into memory.
+.\"
+.SH NOTES
+The low-level terminfo interface is initialized using
+\fB\%setupterm\fP(3X).
+The upper-level curses interface uses the low-level terminfo interface,
+internally.
+.\"
+.SH PORTABILITY
+X/Open Curses does not describe any of these except for \fBcur_term\fP.
+(The inclusion of \fBcur_term\fP appears to be an oversight,
+since other comparable low-level information is omitted by X/Open).
+.PP
+Other implementations may have comparable variables.
+Some implementations provide the variables in their libraries,
+but omit them from the header files.
+.PP
+All implementations which provide terminfo interfaces add definitions
+as described in the \fBTerminfo Names\fP section.
+Most, but not all, base the definition upon the \fBcur_term\fP variable.
