C++ (Cpp) _Scanf Examples

Example #1

File: FSCANF.C Project: Justme0/CLIB

int (fscanf)(FILE *str, const char *fmt, ...)
	{	/* read formatted from stream */
	int ans;
	va_list ap;

	va_start(ap, fmt);
	ans = _Scanf(&scin, str, fmt, ap);
	va_end(ap);
	return (ans);
	}

Example #2

File: fscanf.c Project: vocho/openqnx

            : ungetc(ch, (FILE *)str));
}

int (fscanf)(FILE *_Restrict str, const char *_Restrict fmt, ...)
{   /* read formatted from stream */
    int ans;
    va_list ap;

    va_start(ap, fmt);

#else
    _Unlockfileatomic(stdin);
