vsscanf()               Read Formatted Input from String

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

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

    vsscanf() reads data stored in the character string 's' into
    locations given by the address arguments from the va_arg array
    va_list 'param'.  vsscanf() performs like scanf(), but reads its data
    from a string instead of stdin and stores the data into locations
    given by the arguments in 'param'.

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

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