Hello just want to ask whether I can use file management in uVision3? Because I tried to use which is this " file *fp;" but i say file is an undefined identifier. What should I do to open a file to read and write can anyone tell me thanks!
The reason why I want to open a file to read and write is because I want to pass value from other program to this program. If anyone know the other method can teach me please thank alot!
Ask the real question and you will get a sensible answer. some C compilers provides File access function as a library. But Systems such as windows may want you to use their own libraries.
