函数名: strtok
功 能: 查找由在第二个串中指定的分界符分隔开的单词
用 法: char *strtok(char *str1, char *str2);
程序例:
#include <string.h>
#include <stdio.h>
int main(void)
{
char input[16] = "abc,d";
char *p;
/* strtok places a NULL terminator
in front of the token, if found */
p = strtok(input, ",");
if (p) printf("%s/n", p);
/* A second call to strtok using a NULL
as the first parameter returns a pointer
to the character following the token */
p = strtok(NULL, ",");
if (p) printf("%s/n", p);
return 0;
}

带有_r的函数主要来自于UNIX下面。所有的带有_r和不带_r的函数的区别的是:带_r的函数是线程安全的,r的意思是reentrant,可重入的。
上述程序运行的结果是
abc
d
