test.cpp@ 65717

最後變更在這個檔案從65717是 62915,由 vboxsync 提交於 8 年前
IPRT/test: Added RTTestDisableAssertions and RTTestRestoreAssertions with RTTestI aliases. This simplifies the use of RTAssertSetQuiet/MayPanic by keeping the saved state in the test handle and dealing with nesting, thus reducing the code necessary when testing error paths in APIs which uses assertions.
