Subject: Is there a way to get "EINVAL" style string
Date: Sun, 22 Apr 2012 12:14:04 +0100	[thread overview]
Message-ID: <4F93E7FC.1020904@jguk.org> (raw)

Hello

I was looking at the man pages looking for a way to get a string of the 
errno value meaning. This is kind of a user question.

This API returns "returns a pointer to a string that describes the error 
code":

http://man7.org/linux/man-pages/man3/strerror.3.html

However, this is a description, e.g. "Invalid argument".  Is there a 
function that would return "EINVAL" or "ENOENT" as the string?

Could I suggest that the text on the man page be updated to clarify what 
would be returned:

"returns a pointer to a string that describes the error code. e.g. 
"Invalid argument" if EINVAL was the errnum."

Best regards, Jon
