Setting the current directory of a running app in C++ - c++

Question

The following answer gives a solution using C#, I was wondering what the equivalent would be if one were using only c++ (not c++\cli)
System.IO.Directory.SetCurrentDirectory(System.AppDomain.CurrentDomain.BaseDirectory);
Is there anything in boost that might do the trick?
Based on this problem I've been having: Correctly creating and running a win32 service with file I/O

Answer 1

SetCurrentDirectory (in Win32):
http://msdn.microsoft.com/en-us/library/windows/desktop/aa365530%28v=vs.85%29.aspx
current_path in boost::filesystem:
http://www.boost.org/doc/libs/1_51_0/libs/filesystem/doc/reference.html#current_path
The equivalent for BaseDirectory might be GetModuleFileName (with a null handle for the first argument), followed by GetFullPathName to get the directory from the executable path.

Answer 2

Use SetCurrentDirectory WINAPI.
There is one more answer available at What is the difference between _chdir and SetCurrentDirectory in windows?
Perhaps there is a need for Module Name as well(Seems from comments),Here is one from my old store:-
int main()
{
char path[MAX_PATH]={0};
GetModuleFileName(0,path,MAX_PATH);
}

Answer 3

In Windows, the complete equivalent of
System.IO.Directory.SetCurrentDirectory ( System.AppDomain.CurrentDomain.BaseDirectory )`
would be:
// Get full executable path
char buffer[MAX_PATH];
GetModuleFileName(NULL, buffer, MAX_PATH);
// Get executable directory
boost::filesystem::path path(buffer);
path = path.parent_path();
// Set current path to that directory
boost::filesystem::current_path( path );
Note that there is no platform-agnostic way to get an application's directory, as C++ doesn't recognize the concept of directories in the standard. Boost doesn't appear to have an equivalent function either.
