2.2 Functions
=============
If a function is global, its name must be prefixed with grub_ and must
consist of only small letters. If the function belongs to a specific
function module, the name must also be prefixed with the module name.
For example, if a function is for file systems, its name is prefixed
with grub_fs_. If a function is for FAT file system but not for all
file systems, its name is prefixed with grub_fs_fat_. The hierarchy is
noted this way.
After a prefix, a function name must start with a verb (such as get
or is). It must not be a noun. Some kind of abbreviation is permitted,
as long as it wouldn't make code less readable (e.g. init).
If a function is local, its name may not start with any prefix. It
must start with a verb.
