How to write a function read line from a file in FDK?

Hi Russ,

That is the answer I am looking for.

Thank you again.

Thai,

You can use the "channel" functions for this. I'm far from an expert on channel programming but I've read files line-by-line successfully by going one character at a time, looking for a carriage return.

You can open up the file channel with something like:

  ChannelT chan;
 
  FilePathT *path;
 
  UCharT ptr[1];
 
  IntT numRead;

  path = F_PathNameToFilePath("C:\\temp\\mydoc.txt", NULL, FDefaultPath);
  if((chan = F_ChannelOpen(path,"r")) == NULL)
      return;

  //read the first character
  numRead = F_ChannelRead(ptr, sizeof(UCharT), 1, chan);

...then you can call F_ChannelRead iteratively to build the string in a buffer, looking for a carriage return (ASCII 13) and stopping there. (that is, ptr[0] == 13).

There might be a better way. This is just the way I've gotten it to work. It probably is not a good method for unicode files.
