/**
* g_format_size:
* @size: a size in bytes
*
* Formats a size (for example the size of a file) into a human readable
* string. Sizes are rounded to the nearest size prefix (kB, MB, GB)
* and are displayed rounded to the nearest tenth. E.g. the file size
* 3292528 bytes will be converted into the string "3.2 MB".
*
* The prefix units base is 1000 (i.e. 1 kB is 1000 bytes).
*
* This string should be freed with g_free() when not needed any longer.
*
* See g_format_size_full() for more options about how the size might be
* formatted.
*
* Returns: a newly-allocated formatted string containing a human readable
* file size
*
* Since: 2.30
