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 pa- + rameter to set_term, for switching between screens.

+ 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 applica- + tions, although the hash-tables used by the terminfo and termcap func- + tions are not available. + + The long terminfo capability names use a "l" (ell) in their names: + boolfnames, numfnames, and strfnames. + + These are the short names for terminfo capabilities: boolnames, num- + names, and strnames. + + These are the corresponding names used for termcap descriptions: bool- + codes, numcodes, and strcodes. + + +
+ A terminal description begins with one or more terminal names separated + by "|" (vertical bars). On initialization of the curses or terminfo + interfaces, setupterm(3x) copies the terminal names to the array tty- + type. + + +
+ In addition to the variables, <term.h> also defines a symbol for each + terminfo capability long name. These are in terms of the symbol CUR, + which is defined + + #define CUR ((TERMTYPE *)(cur_term))-> + + These symbols provide a faster method of accessing terminfo capabili- + ties than using tigetstr(3x), etc. + + The actual definition of CUR depends upon the implementation, but each + terminfo library provides these long names defined to point into the + current terminal description loaded into memory. + + +
