Follow-up Comment #3, patch #9339 (project lwip):

Sorry, I don't understand your comment #2. I can't return an int for function
declared to return an int?

- slot >= 0 is valid slot number and .
- all negative value are error code (ERR_MEM if no free slot, ERR_VAL if
invalid param).

Should I change return value of the function to 'int' instead of 'err_t'
(which is an 'int' ?)
