- This implementation can be configured to provide rudimentary support
- for multi-threaded applications. This makes a different set of
- libraries, e.g., <STRONG>libncursest</STRONG> since the binary interfaces are different.
-
- Rather than modify the interfaces to pass a thread specifier to each
- function, it adds a few functions which can be used in any
- configuration which hide the mutex's needed to prevent concurrent use
- of the global variables when configured for threading.
-
- In addition to forcing access to members of the <STRONG>WINDOW</STRONG> structure to be
- via functions (see <STRONG><A HREF="curs_opaque.3x.html">curs_opaque(3x)</A></STRONG>), it makes functions of the common
- global variables, e.g., COLORS, COLOR_PAIRS, COLS, ESCDELAY, LINES,
- TABSIZE curscr, newscr and ttytype. Those variables are maintained as
- read-only values, stored in the <STRONG>SCREEN</STRONG> structure.
-
- Even this is not enough to make a thread-safe application using curses.
- A multi-threaded application would be expected to have threads updating
- separate windows (within the same device), or updating on separate
- screens (on different devices). Also, a few of the global variables
- are considered writable by some applications. The functions described
- here address these special situations.
