| * Change order of variables in appveyor build matrixPali Rohár2020-11-041-97/+97
|/ | | | | | | | | This change no function effect as it changes only order of defined variables. The only visible change is on appveyor web where variables are printed in other as they are defined. If list of variables is too long, variables defined later are hidden on the web interface. Variable APPVEYOR_BUILD_WORKER_IMAGE was moved to the end of list as it is less important to know as variable GENERATOR (defines which compiler is used).

| | | | | | | | | | | | According to https://cmake.org/pipermail/cmake/2013-May/054792.html cmake 2.8.11 was released in 2013, so we can assume that no older version will be used anymore.

| * Replace VirtualQueryEx() call by GetModuleHandleExA() callPali Rohár2020-07-141-16/+2
|/ | | | | | | | | | | | Usage of VirtualQueryEx() call is needed for retrieving HMODULE of passed function address and it is just an undocumented hack. Based on @rhabacker's tests it is unstable and does not work correctly. https://github.com/dlfcn-win32/dlfcn-win32/pull/72#issuecomment-656581418 So replace VirtualQueryEx() call by standard GetModuleHandleExA() function with special GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS flag which should do the same thing but it is documented and it is working correctly.

|/ | | | | | | | | | error occurred It does not make sense to pass file variable (which is NULL) to function save_err_ptr_str() which converts its argument to string. We can call directly save_err_str() with string value. Also it is highly unexpected that GetModuleHandle(NULL) call fails.

| | | | | | | | | | ISO C90 forbids mixed declarations and code ISO C++ forbids converting a string constant to 'char*'
| * Fix gcc warning: ISO C forbids return between function pointer and void *Pali Rohár2019-07-253-37/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using compiler specific pragma to disable particular warning, rewrite code which cast from function pointer to data pointer according to POSIX dlopen() documentation. This also fix compile warning under MSVC. According to the ISO C standard, casting between function pointers and 'void *', as done above, produces undefined results. POSIX.1-2003 and POSIX.1-2008 accepted this state of affairs and proposed the following workaround: *(void **) (&cosine) = dlsym(handle, "cos"); This (clumsy) cast conforms with the ISO C standard and will avoid any compiler warnings.
| * Fix gcc warning: comparison between signed and unsigned integer expressionsPali Rohár2019-07-251-3/+4
| | | | | | | | | | GetTempPathA() returns DWORD (32/64bit unsigned integer) and not int (32 signed integer).
| * Do not include intrin.h filePali Rohár2019-07-251-1/+0
|/ | | | | | | | | | | | Include file intrin.h is not needed for compiling dlfcn.c as _ReturnAddress intrinsic is defined in dlfcn.c manually. Moreover _ReturnAddress is available only as an intrinsic, there is no function implementation. So even including intrin.h file does not provide function variant for _ReturnAddress. More important, include file intrin.h is not available in older Windows Driver Kit 7.1.0. So removing usage of intrin.h file makes compilation of dlfcn-win32 also under these older WDK versions.

|/ | | | | | Function save_err_str() checks for error by GetLastError() call. Calling EnumProcessModules() may change or reset it. So call save_err_str() immediately after LoadLibraryExA().
