/**
* qemu_find_file:
* @type: QEMU_FILE_TYPE_BIOS (for BIOS, VGA BIOS)
* or QEMU_FILE_TYPE_KEYMAP (for keymaps).
* @name: Relative or absolute file name
*
* If @name exists on disk as an absolute path, or a path relative
* to the current directory, then returns @name unchanged.
* Otherwise searches for @name file in the data directories, either
* configured at build time (DATADIR) or registered with the -L command
* line option.
*
* The caller must use g_free() to free the returned data when it is
* no longer required.
*
* Returns: a path that can access @name, or NULL if no matching file exists.
