Sending data to .csv file

Hi 🙂 I want to write some data to .csv file.

I took an example : \zephyrproject\zephyr\samples\subsys\fs\fat_fs and I added these to my code:

In main:

Os_x, os_y, os_z - these are variables I wanna have in one row in .csv file.

The code compiles, but in terminal I get:

What can be the reason of this problem?
 I also tried fs_opendir (&zfp, "C:/Users/user/Desktop/file.csv") but it also doesnt work 🙁
