How do I get the MATLAB current directory in mex code?

In matlab it would be pwd, but in mex code, how would I find out?

The current folder inside the MEX file is the same as in Matlab. So you can use the standard C command getcwd to obtain the current directory. A modern version is _getcwd or if you are using the boost libs: current_path(). Under Windows the GetCurrentDirectory is sufficient also and can handle Unicode filenames in addition, but is depends on the platform.
