Function Documentation

ZTEST_USER() [1/2]

ZTEST_USER	(	kernel_sys_sem	,
		test_multi_thread_sem_limit
	)

#include <tests/kernel/semaphore/sys_sem/src/main.c>

Test max semaphore can be give and take with multiple thread.

• Define and initialize semaphore and thread.
• Give sem by multiple threads.
• Verify more than max count about semaphore can reach.
• Take sem by multiple threads and verify if sem count is correct.

ZTEST_USER() [2/2]

ZTEST_USER	(	kernel_sys_sem	,
		test_multiple_thread_sem_usage
	)

#include <tests/kernel/semaphore/sys_sem/src/main.c>

Test semaphore usage with multiple thread.
