_stscanf_s 函数

MSDN 对这个函数描述。Example:

// crt_sscanf_s.c
// This program uses sscanf_s to read data items
// from a string named tokenstring, then displays them.
 
#include <stdio.h>
#include <stdlib.h>

<!-- more -->
 
int main( void )
{
   char  tokenstring[] = "15 12 14...";
   char  s[81];
   char  c;
   int   i;
   float fp;
 
   // Input various data from tokenstring:
   // max 80 character string plus NULL terminator
   sscanf_s( tokenstring, "%s", s, _countof(s) );
   sscanf_s( tokenstring, "%c", &c, sizeof(char) );
   sscanf_s( tokenstring, "%d", &i );
   sscanf_s( tokenstring, "%f", &fp );
 
   // Output the data read
   printf_s( "String    = %s\n", s );
   printf_s( "Character = %c\n", c );
   printf_s( "Integer:  = %d\n", i );
   printf_s( "Real:     = %f\n", fp );
}

sscanf_s 取值的时候，需要在每个取值后面指定取值的最大大小。

#include "stdafx.h"
 
#include <stdio.h>
#include <stdlib.h>
 
int _tmain()
{ 
    TCHAR str[] = _T("CSFS dfdfd");
    TCHAR szBuff[100] = {0};
    TCHAR szBuff2[100] = {0};
    _stscanf_s(str, _T("%s%s"), szBuff, _countof(szBuff), szBuff2, _countof(szBuff2));
    _tprintf(_T("%s\n%s\n"), szBuff, szBuff2);
 
    return 0;
}
