Please update the function comment: explain that it returns 1 and copy it into value if found, or return 0 on error or if not found. Something like that.
I'm not sure why key is a parameter: its value is always "home". Maybe write a following PR to remove the key parameter? (need to update getpath.c and getpathp.c)

Note: I'm not sure why fseek(0) is called: we just opened the file in read mode, not in append mode, the file cursor should already be 0.

Thank you very much for your review, @vstinner. I have removed the fseek() call -- it indeed seems to be unneeded.
I will create a pull request to remove the key parameter.
There doesn't appear to be any need for it.

I don't think that it's worth it to backport this change to Python 3.7 or 3.8. |
