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!
