Just for the sake of clarification ... What value are you specifying for p_dir variable?
It should be a directory object created in the database.
It can be created with a command like
CREATE OR REPLACE DIRECTORY BFILE_DIR AS 'e:\middle-east\ssm';
and the user who is going to call the function should have read access on this directory object which can be granted with a command like
grant read on directory BFILE_DIR to FUNCTIONCALLINGUSER;
I hope this helps with what you are trying
