<pre>
原型：extern int strcspn(char *s1,char *s2);
用法：#include <string.h>
功能：在字符串s1中搜寻s2中所出现的字符。
说明：返回第一个出现的字符在s1中的下标值，亦即在s1中出现而s2中没有出现的子串的长度。
举例：
// strcspn.c
#include <syslib.h>
#include <string.h>
main()
{
char *s="Golden Global View";
char *r="new";
int n;
clrscr();
n=strcspn(s,r);
printf("The first char both in s1 and s2 is: %c",s[n]);
getchar();
return 0;
}
