Mac OS X-在文件中获取行尾

Question

I try to open and read a file on Mac OS X:

FILE * pFile = fopen (path_.c_str() , "r");
if (pFile == NULL)
{
   perror ("Error opening file");
}
else
{
   char line [buffer_size]={0};
   size_t length=0;
   std::vector<unsigned> nodes;
   while ((line[length++] = fgetc (pFile)) != EOF )
   {
      printf("%d",line[length-1]);
      if (line[length-1] == '\r'||line[length-1] == '\n'
#ifdef __APPLE__
    ||line[length-1] == '$'
#endif
      )
{
   line[length-1]=0;
   unsigned number = 0;
   for(unsigned i=0;i<length;++i)
   {
      if(isdigit(line[i]))
   {
      number = number *10+line[i]-'0';
   }
else
   {
      nodes.push_back(number);
      number = 0;
   }
}
      memset(&line,0,buffer_size);
      length=0;
}
}
fclose (pFile);

I use #ifdef __APPLE__ define, this code work perfectly on Linux, but on Mac OS XI now must read some symbol which defines end of line for my file/line. How can I get which symbol finished file, without this trick?

Answer 1

Do it all in C++:

unsigned number;
std::vector<unsigned> nodes;
std::ifstream file(path_.c_str());
while (file >> number)
    nodes.push_back(number);

Answer 2

As you can see it here , OSX new line character is now \\n , don't worry about that.

So, you don't have to make any Apple specific code, except if you want to support a Mac OS version <= 9 .
