| #define NUT_THREAD_STACK_ADD 0 |
Stack size summand.
The specified value will be added to all configured stack sizes.
| #define NUT_THREAD_STACK_MULT 1 |
Stack size factor.
Configured stack sizes are multiplied with this value.
All stack size settings of internal Nut/OS threads had been calculated for size optimized code. Probably more stack space is required with other compiler settings.
For example, when GCC generates non-optimized code for source code debugging, a factor of 3 should be applied to all stack sizes.
Application code may also make use of this macro.
#include <sys/thread.h> #define MY_THREAD_STACK ((384 * NUT_THREAD_STACK_MULT) + NUT_THREAD_STACK_ADD) NutThreadCreate("myth", ThreadFunc, 0, MY_THREAD_STACK);
See also NUT_THREAD_STACK_ADD.
| #define TDS_READY 2 |
