Could you please explain the problem that this change is fixing?

drvoss commented 3 years ago

@jkotas #define symLoad GetProcAddress The #define statement takes two strings. first identifier and second token-string. The #define line occurs compile error. ref : https://docs.microsoft.com/en-us/cpp/preprocessor/hash-define-directive-c-cpp?view=vs-2019

#include <unistd.h>
// ..
#ifndef F_OK
#define F_OK    0
#endif

Visual C++ has no unistd.h. It's for linux. So, if It can't find the F_OK definition, defined it.

HINSTANCE handle = LoadLibraryA(path); The default LoadLibrary defines LoadLibraryW. It takes Unicode as an argument. Path is ansi string. So I fix it LoadLibraryA. ref : https://docs.microsoft.com/en-us/windows/win32/api/libloaderapi/nf-libloaderapi-loadlibraryw
