从字符串(char *)删除空格尾 [英] remove whitespaces tail from string (char*)

问题描述

你好，我有带行格式的文本文件

hello I've got text file with lines format

1|few ewf ew fewfew 

我需要解析它，但是我不知道如何从我不知道的第二个值中删除空格尾.

I need to parse it but I don't know how can I drop whitespaces tail from second value I don't know.

这是我到目前为止的segmentation fault尝试

Here is my segmentation fault try so far

char* token1;
char* token2;
char* search = "|";
char* search2 = "  "; // double space because string can contains single space
while (fgets(line, 150, f)) {
  token1 = strtok(line, search);
  token2 = strtok(search, search2); // <- segfault
  //token2 = strtok(NULL, search); <- contains a lot of spaces in tail
