mastef / isexist_vs_isnotexist.go
Created February 4, 2016 08:30
os.IsExist(err) vs os.IsNotExist(err)
Watch out, os.IsExist(err) != !os.IsNotExist(err)
They are error checkers, so use them only when err != nil, and you want to handle
specific errors in a different way!
Their main purpose is to wrap around OS error messages for you, so you don't have to test
for Windows/Unix/Mobile/other OS error messages for "file exists/directory exists" and
"file does not exist/directory does not exist"
