fscanf with CCS

hdp
Intellectual 330 points

I have a text file that I am reading using CCS using the function fscanf(). I can only read couple of values in the txt file and after that the fscanf function does not successfully read data from the txt anymore.

Here is the fscanf statement: SCAN_COUNT = fscanf(file, "%f", &value);

 

Questions:

1) Shouldn't fscanf work?

2) Is there a document identifying what standard C functions that can be used with CCS.

3) Is there a more effective way to read a file (large memory size) from the computer into the processor memory using CCS?

 

Thanks!

    Hi,

    If the function fscanf does not find the format compatible with what is in the file, it will not work.  So if it is reading integer (%d), it will work as long as the file has numbers that are spaced - when it finds something wrong with the format, fscanf will stop reading. The same will happen when reading the characters %c - if it does not find the proper character format, it will stop reading. So this might be one of your problems - what is in the file is not in one proper format. 

    For formats, you can look for "length modifiers" in this page (not a TI page):

    TI does not provide this documentation because we do not own the standard C. You can search the Internet or try buying a book.

    I would suggest you to use fread - it does not have the problems with format that fscanf has.
