SGX Protected FS returning NULL

[__260]

Team,
Tried to read a file stored on disk using Intel SGX protected File system function fopen_auto_key(). But the file pointer is returning null. Unable to read the file.
The code I'm using,

SGX_FILE* fp = sgx_fopen_auto_key("sealed_file.txt", "r+");

Kindly help to figure out the possible issue.

Hi,

Are you specifying the full path of the file in the first argument?

Sincerely,

Sahira
