Subject: Problem reading /proc/acpi/battery/BAT0/info
Date: Sat, 28 Aug 2004 23:20:38 -0500 [thread overview]
Message-ID: <20040829042038.GA8073@digitasaru.net> (raw)
Hello.
I'm writing some code to read battery status, but am having problems reading
/proc/acpi/battery/BAT0/info.
If I read that file, I can fill *one* and *only one* buffer before I get
EOF (read returns 0 bytes read on the next buffer). This is regardless
of buffer length--I can use 1 or 3 or 10 bytes. First read succeeds,
second read fails. Errno is 0.
With the *same code*, I can read the entire file without issue.
Any hints as to what's going on here?
Thanks!
Puzzled,
-Joseph
