config PDCURSES_MULTITHREAD
|
|
bool "Enable code for running pdcurses from multiple threads (removes global variables)."
|
|
default n
|
|
---help---
|
|
The base pdcurses code uses global and function static variables,
|
|
preventing multiple tasks from using pdcurses in a FLAT model.
|
|
This option collects all those variables into a thread specific
|
|
dynamically allocated context, enabling mulitple tasks to use
|
|
pdcurses concurrently at the cost of a slight execution speed
|
|
penalty for performing per task context lookup.
|
|
|
|
config PDCURSES_MULTITHREAD_HASH
|
|
bool "Use PID HASH lookup for thread specific pdcurses context data."
|
|
depends on PDCURSES_MULTITHREAD
|
|
default n
|
|
---help---
|
|
Without this option, the per task pdcurses logic uses a linked list
|
|
of allocated contexts, keeping RAM usage to a minimum at the expense
|
|
of execution time for semaphore locking / unlocking and list traversal.
|
|
This option enables a PID hash lookup option which eliminates the
|
|
need for this extra logic by using a statically allocated array of
|
|
context pointers whose size is dictated by the MAX_TASKS config variable.
|
|
|
|
Enabling this option allows simple hash calculation and array lookup at
|
|
the expense of extra RAM usage for the static array of context pointers.
|
|
|
|
config PDCURSES_SHORT_ALTCHARSET
|
|
bool "Allow alternate character set with short 16-bit chtype"
|
|
depends on !PDCURSES_CHTYPE_LONG && !PDCURSES_FORCE_UTF8
|
|
default y
|
|
---help---
|
|
The alternate character set includes graphic line drawing characters
|
|
used for drawing box borders. When using 16-bit chtype, the base
|
|
pdcurses does not define a bit for A_ALTCHARSET. This option uses
|
|
the MSB of the 8-bit character code as A_ALTCHARSET to enable line
|
|
drawing characters.
|
|
|
|
Enabling this means limiting the usable normal character set to the
|
|
base 7-bit ASCII characters, however for most VT-100 / ANSI emulators,
|
|
the upper bits are either not defined or not critical.
