c - How to mount image using mount(2) -


i cannot mount image on macosx 10.10 via c function mount().

i use following code

...     char imgpath[m_imgname.size() + 1];     memcpy(imgpath, m_imgname.c_str(), m_imgname.size() + 1);     struct hfs_mount_args data;     data.fspec = imgpath;     if(mount("hfs+", m_targetpath.c_str(), mnt_rdonly, &data)){         throw syscalltestexeption(errno, "mount() failed!", get_file_line_func_arg);     } ...

and when start program error "mount() failed! error(operation not supported device)."

and image mounted if use following command:

sudo hdiutil attach -mountpoint "${mountpointpath}" "${image}"

also, when use mount() on linux - ok. following linux code:

... if(mount(m_imgname.c_str(), m_targetpath.c_str(), m_fstype.c_str(), 0, m_opts.c_str())){         throw syscalltestexeption(errno, "mount() failed!", get_file_line_func_arg);     } ...

there no hfs+ type in

mount("hfs+", m_targetpath.c_str(), mnt_rdonly, &data)

you should use hfs handle both hfs , hfs+. example @ mount_hfs command source:

#define hfs_mount_type              "hfs"
