strtok() 函数

 

strtok

语法:

#include <string.h>   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"
