how to save data into file in keil IDE

hi
I want to save my intermediate data into a file.
I tried to use fopen, fwrite, it can not even read. how should i use rtl.h ?

  int  count[10];
  FILE *fout;

  fout = fopen ("Counter.bin","w");
  if (fout != NULL) {
    fwrite (&count[0], sizeof (int), 10, fout);   // write an item 10 times to the file
    fclose (fout);

my keil version 4.6
ARM core is cortex-M0.
I am using the startup_MPS_CM0.s startup file to do the work.

Thanks for help!

Thanks for reply!

I want to save a long array into a file, this file can be .hex or .bin format.
it is good to do this in the c coding.

The LOG or SLOG are the commands, similar as SAVE. can you give an example about your suggestion?

Thanks again.
