Various fixesFix noinline for older compiler versions (e.g. Visual Studio 6.0)2021-02-03T20:01:24+00:00Pali Rohárpali.rohar@gmail.com2021-02-03T20:01:24+00:00urn:sha1:9e40646cf3a7d0817b2298f915399a128fcb4d27
Visual Studio 6.0 does not support __declspec(noinline) and throw error.
Add checks for compilers which support noinline to prevent compile errors.
Define ULONG_PTR for older SDK2021-02-03T20:00:56+00:00Pali Rohárpali.rohar@gmail.com2021-02-03T20:00:56+00:00urn:sha1:7da1054564609f3382869714432f54b63812d083
If compiling with _WIN32_WINNT target prior 0x0500 then SDK does not define
ULONG_PTR type. Such systems are only 32bit so define it explicitly to
32bit type ULONG.
Fix MSVC 14.00 compile warning: warning C4244: '=' : conversion from 'ULONG_PTR' to 'char', possible loss of data2021-02-03T20:00:28+00:00Pali Rohárpali.rohar@gmail.com2021-02-03T20:00:28+00:00urn:sha1:d1a0d28f903f9d3eff03f06e299cde5a7998216eAdd helper function MyGetModuleHandleFromAddress()2021-02-03T19:59:58+00:00Pali Rohárpali.rohar@gmail.com2021-02-03T19:59:58+00:00urn:sha1:06fea3fe8b3efe8c79f97fa724f703bc0e25aeef
This function implements calling GetModuleHandleExA() with correct flags to
retrieve hModule from passed address.
To allow compilation also with older compilers and environments (like WDK)
with any _WIN32_WINNT value, retrieve pointer to this function via
GetProcAddress(). And as a fallback implementation use old code via
VirtualQuery() which was there prior commit 8ec5ffef2eca.
Fix helper function MyEnumProcessModules()2021-02-03T19:59:18+00:00Pali Rohárpali.rohar@gmail.com2021-02-03T19:59:18+00:00urn:sha1:0e9d85a9d03bcedade35cced63ec6b969ab3451e
Call SetErrorMode(SEM_FAILCRITICALERRORS) prior opening Psapi.dll library
to avoid GUI error messages.
Close Psapi.dll library via FreeLibrary() if symbol was not retrieved to
prevent possible memory leaks.
Try to get K32EnumProcessModules symbol from Kernel32.dll library as it is
preferred way how to call EnumProcessModules() on Windows 7 and newer
versions.
If retrieving EnumProcessModules symbol failed with both methods then do
not try it again on next MyEnumProcessModules() function call.
Avoid calling SetLastError() and GetLastError() internally2021-02-03T19:58:39+00:00Pali Rohárpali.rohar@gmail.com2021-02-03T19:58:39+00:00urn:sha1:c172ee216cd5d46c1999018e1a3e905eebe3c10c
There is no need for propagating internal errors via SetLastError() and
GetLastError() calls. Just use additional argument for save_err_str()
function. Also dlfcn API is POSIX and does not use GetLastError().
