I'm trying to port a unix application to cygwin, and I have two big questions: 1) When do I use the mingw header files, and when do I use the regular header files? For example, there are two copies of stdio.h, one in /usr/include/mingw and one in /usr/include, and both are different. Also, values.h is only in mingw, and the application wants this header file--is it safe to include it as <mingw/values.h>? 2) The application makes use of FILE struct internals, but these are not defined in stdio.h. How do I work around the FILE->_IO_read_ptr and FILE->_IO_read_base usage? It looks like cygwin uses some __sFILE structure instead of the _IO_FILE struct from linux. The application compiles and runs fine on linux. -- _______________________________________________ Make PC-to-Phone calls with Net2Phone.
