version - NCurses: how to find out whether ABI 6 is supported? -


is there way find out whether ncurses supports abi 6?

if ( abi 6 supported ) {     ... } else {     ... }

you can see comparing header files. there 2 features can checked @ compile time:

  • the mouse version differs in header files:
      /*                                                                                    * identify mouse encoding version.                                               */                                                                                 -#define ncurses_mouse_version 1                                                     +#define ncurses_mouse_version 2
  • the extended-colors symbol defined:

that is, latter (in abi 5) within ifdef prevents ncurses_ext_colors symbol being defined. ncurses_mouse_version symbol defined, value changed.
