vscanf()                Perform Formatted Input from Stdin

 #include   <stdio.h>
 #include   <stdarg.h>

 int        vscanf(format-string,param);
 const char *format-string;              Format string
 va_list    param;                       Variable argument list

    vscanf() reads data from 'stdin' one character at a time, formats the
    data according to the given 'format-string', and stores it in the
    locations given by the address arguments from the va_arg array
    va_list 'param'.

    See scanf() for a complete description of the format-string.

    See va_arg() for a description of variable argument lists.
