strtok

char *strtok( char *str1, const char *str2 );

功能:函数返回字符串str1中紧接“标记”的部分的指针, 字符串str2是作为标记的分隔符。如果分隔标记没有找到,函数返回NULL。为了将字符串转换成标记,第一次调用str1 指向作为标记的分隔符。之后所以的调用str1 都应为NULL。

例如:

char str[] = "now # is the time for all # good men to come to the # aid of their country";  
char delims[] = "#";   
char *result = NULL;     
result = strtok( str, delims );     
while( result != NULL ) 
{       
    printf( "result is \"%s\"\n", result );         
    result = strtok( NULL, delims );   
}

以上代码的运行结果是:

result is "now "   
result is " is the time for all "   
result is " good men to come to the "  
 result is " aid of their country"
