Scan input from a file (varargs)
#include <wchar.h> #include <stdarg.h> int vfwscanf( FILE * fp, const wchar_t *format, va_list arg );
- The stream that you want to read from.
- A wide-character string that specifies the format of the input. For more information, see scanf(). The formatting string determines what additional arguments you need to provide.
- A variable-argument list of the additional arguments, which you must have initialized with the va_start() macro.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The vfwscanf() function scans input from the file designated by fp, under control of the argument format.
The number of input arguments for which values were successfully scanned and stored, or EOF if the scanning reached the end of the input stream before storing any values.
