commit a7dd057ce2b622aa2d7aaf3abb993c9e50fb2dd3 Author: George Bișoc <[email protected]> AuthorDate: Sat Jun 6 17:47:38 2020 +0200 Commit: GitHub <[email protected]> CommitDate: Sat Jun 6 17:47:38 2020 +0200 [NTDLL_APITEST] Add ProcessBasePriority and ProcessRaisePriority classes unit tests (#2740) ProcessRaisePriority expects a buffer input information argument of KPRIORITY type definition as shown in this documentation (see the PROCESS_INFORMATION_CLASS structure members list of classes). https://undocumented.ntinternals.net/index.html?page=UserMode%2FUndocumented%20Functions%2FNT%20Objects%2FProcess%2FNtSetInformationProcess.html --- .../apitests/ntdll/NtSetInformationProcess.c | 143 +++++++++++++++++++++ 1 file changed, 143 insertions(+) diff --git a/modules/rostests/apitests/ntdll/NtSetInformationProcess.c b/modules/rostests/apitests/ntdll/NtSetInformationProcess.c index b5fcc18e2db..0b805b3ca66 100644 --- a/modules/rostests/apitests/ntdll/NtSetInformationProcess.c +++ b/modules/rostests/apitests/ntdll/NtSetInformationProcess.c @@ -7,6 +7,147 @@ #include "precomp.h" +static +void +Test_ProcBasePriorityClass(void) +{ + NTSTATUS Status;
