c++ - 以编程方式使用 UTF8 挂载 FAT32 文件系统

Question

如何使用“mount()”函数(来自“mount.h”，参见“man 2 mount”)以 UTF8 挂载的方式挂载 FAT/FAT32 设备？

这是我现在用来挂载它的相关代码:

mount_result = mount(device_node, device_mount_point, fstype, MS_NOATIME, "");

谢谢，尼古拉

Answer 1

来自manpage :

The data argument is interpreted by the different file systems. Typically it is a string of comma-separated options understood by this file system.

来自 mount(8) 的联机帮助页, "vfat 的挂载选项":

utf8 : UTF8 is the filesystem safe 8-bit encoding of Unicode that is used by the console. It can be be enabled for the filesystem with this option. If 'uni_xlate' gets set, UTF8 gets disabled.

因此，这应该会为您提供所需的行为:

mount_result = mount(device_node, device_mount_point, fstype, MS_NOATIME, "utf8");
