我试图消除^ M在每行的结尾，并在C以下

I am trying to remove ^M at the end of each line, and have the following in C

GLOBAL BOOLEAN CARRIER_CONSIGNOR_SIM_ReplaceZPL(CARRIER_CONSIGNOR_SIM_ORDER_TYPE* Header)
{
  #define MAX_FILE_LEN 30

  char filename[MAX_FILE_LEN];
  snprintf(filename, MAX_FILE_LEN, "%s.zpl", Header->OrderNumber);

  FILE *file;
  FILE *write;
  char line  [256];
  char linec [256];

  file = fopen( filename, "r");
  write = fopen( filename, "r+");

  if( file != NULL )
  {
    while ( fgets ( line, sizeof line, file ) != NULL ) /* read a line */
    {
      strcpy(linec, line);
      fprintf (write , linec);
    }
    /* Close both files */
    fclose (write);
    fclose (file);
    printf("REPLACED LABEL in %s\n", filename);
    return ( TRUE );
  }

 return ( FALSE );
}/*CARRIER_CONSIGNOR_SIM_ReplaceZPL*/

我曾尝试做以下为RB +，R + B和Rb来写= FOPEN但无论这将消除^ M什么是解决这个问题的最好办法。

I have tried doing the following to "rb+", "r+b and rb to the write = fopen but neither of this will remove ^M. What is the best way around this.

推荐答案

您只需通过删除AY \\ r 或 \\ n缩短字符串结尾，例如：人物变化：

You can just shorten the string by deleting ay \r or \n characters at the end, e.g. change:

  ...
  strcpy(linec, line);
  ...

到

  int len;
  ...
  strcpy(linec, line);
  len = strlen(linec);                   // get length of string
  while (len > 0)                        // while string not empty
  {                                      // if last char is \r or \n
      if (linec[len - 1] == '\r' || linec[len - 1] == '\n')
      {
          linec[len - 1] = '\0';         // delete it
          len--;
      }
      else                               // otherwise we found the last "real" character
          break;
  }
  ...

请注意，当你打印字符串，您将需要添加一个换行符，例如用

Note that when you print the string you will need to add a line feed, e.g. use

fprintf(write, "%s\n", linec);
