推荐答案

从GNU C库手册 - 的查找令牌中的String ：

From The GNU C Library manual - Finding Tokens in a String:

之间的一个区别 strsep 和 strtok_r 是，如果输入的字符串包含分隔多个字符的行 strsep 返回每个对字符分隔符从一个空字符串。这意味着，一个程序正常应该测试 strsep 处理之前返回一个空字符串。

One difference between strsep and strtok_r is that if the input string contains more than one character from delimiter in a row strsep returns an empty string for each pair of characters from delimiter. This means that a program normally should test for strsep returning an empty string before processing it.
