how to find the size of a file within the file system ?

[ziv123]

hello Nordic

i am working with ncs v2.5.0 with nrf52840 

i am using lfs to save the device configurations in a file

when reading this file i need to allocate a buffer for it and i am surprise that i did not find any API for that

there is an api for opendir that includes a field of size and if it is different from zero then it is the a file otherwise its a dir but i am not sure it is the right what to do that  

so, is there a straight foreword API i can use to know the size of the file saved in file system ? 

hope to read you soon

best regards

Ziv

Hello Ziv,

Have you tried using the fs_stat() function as in the littlefs sample here: https://github.com/nrfconnect/sdk-zephyr/blob/f50ad41dd6ea61d36bece05171768e12f5ceb5a3/samples/subsys/fs/littlefs/src/main.c#L190C7-L190C14?

Best regards,

Vidar
