+====== vscanf ======
+<code c>
+int vscanf(char * restrict format, va_list arg_ptr);
+</code>
+=== description ===
+The functions vscanf(), vfscanf(), and vsscanf() are functionally equivalent to scanf(), fscanf(), and sscanf(), respectively, except that the argument list has been replaced by a pointer to a list of arguments. This pointer must be of type va_list, which is defined in the header .
+===== example =====
+<code c>
+#include <stdio.h>
+#include <stdarg.h>
+  void get_message(char *format, ...)
+  {
+    va_list ptr;
+    va_start(ptr, format);
+    vscanf(format, ptr);
+    va_end(ptr);
+  }
+  int main(void)
+  {
+    int i;
+    printf("integer:");
+    get_message(" %d ", &i);
+    printf("%d", i);
+    return 0;
+  }
