Many library functions, especially those related to the operating system, will notify the program that the function call fails when the execution fails through an external variable named errno. The following code uses this feature for error handling: Errno = 0; // * call the library function */If (errno)/* handle errors */ The above processing is incorrect. To understand this, let's assume what may happen when the fopen function is called. When the fopen function requires a new file for
