According to the "official" documentation, vcgencmd measure_temp and the value in /sys/class/thermal/thermal_zone0/temp are different temperatures. The documentation is rather vague on this (as it is on many hardware-related items), but it suggests that vcgencmd provides the GPU temp, and /sys.../temp is the CPU temp. In any event, the values are typically close.

Experience has lead me to believe the high level stream interface is not reliable on proc/sys files, and you should use open() and read() instead -- but YMMV. There's also a "libsysfs", but it's been abandoned and the kernel devs have explicitly told people to stay away from it.
